- Mirror installation next week
FXE:
- Replaced broken diamond-window
SCS:
- Installation of alignment laser
- Mirror tank installation next week
SQS:
SASE tunnels:
- C. Youngman is coordinating the works in the SASE1, 2 and 3 tunnels, daily meetings are at 9:30 every morning.
- Works have been scheduled and planned, most work to happen in SASE3 and SASE2.
- Staff should be aware that works e.g. regarding the vacuum loops have been scheduled and are ongoing, in doubt contact C. Youngman, N. Jardon or V. Bondar
CAS:
- Release test with Karabo 2.2.3 are concluding probably today, including test with PLC firmwares 1.26 and 1.27.
- This would lead to a release for ITDM & Detectors by this evening. A timeslot is required to test the new Karabo with ITDM / DAQ.
- Deployment at the beamline could potentially be in two weeks, if the test with ITDM and Detectors will conclude fine.
XPD:
- Email to xfel-op-allhands was received, indicating that there could have been a shortage of cooling water for the magnets and racks supplied from XS4 and also XS2 (should be SASE2-branch only). If you have electronic racks in this area, check the temperature, email will be forwarded to readiness.
Detectors:
- A single supermodule of the LPD-detector is flickering, is being investigated.
ITDM:
- A rise of the temperature in the balcony room from 27° to 39° was observed in the morning from ca. 6:00 until 6:30.
- This lead to damage at two power supplies.
- There was no indication by MKK or TS about any kind of shortage or shutdown of the cooling water supply.

Subject: RE: adqDigitzer
Hi everybody,
Today morning me, Andreas and Leonce have tested digitizer with software in
FXE hutch. We tried the same configuration as it was and checked the log
file, we observed that software was missing synchronization, that means
either packets from digitizer have some problems ( missed or corrupted) , or
buffers are too small in software. We reinitialized everything and problem
disappeared ( at least for synchronization).
This afternoon I tested digitizer in our lab in APD mode with Raw data mode
and also checked values; everything was fine. Because till today we have
tested digitizer in fully load and enabled APD and raw data for all channels
we observed no issues. I tried to set the same configuration which Andreas
applied in their system ( APD for one channel and raw data for all channels)
I encountered the same problems that he had mentioned in Email. Conclusion
is that Digitizer has no problem when Algorithms are enabled for all
channels. But when one algorithm is enabled for only one channel there is
problem in packets, or even there is no packet from digitizer sometimes.
Which gives timeout error.
Current solution is that to enable required algorithm for all channels and
ignore result from unwanted ones.
I do really apologize for this inconvenience caused and will do my best to
solve the problem in Firmware as soon as possible.
Best,
Hamed

Adriano Violante | General | Information | Status report after dispatch meeting 09.30 | General
Due to the triggering of the emergency power off in FXE caused by electrical works being done on Sunday, FXE and SPB lost beam and electronics was switched off. In general the efficiency of the communication between groups has to be impoved. An important first step is the publication to a easy accessible site of the OCDs phone numbers list. PSPO will organize that.
Comment by PGessler
"It was clear to all, that currently the impact on operation due to emergency power off is severe, since the Racks with the PLC CPUs as well as the MicroTCA systems will be also switched off, what is not what was defined/specified. Therefore it was agreed, that no work on the power distribution/emergency off will be done until the defined date (for FXE 16th April). That work was done there nevertheless is extremely careless. The fact, that this was done on a Sunday and also during user time makes it even much worse then that. It has to be completely followed up and made clear, that this is not acceptable and will not be repeated again!"
SPB
A run of 14 hrs acquiring data was a sort of stress test for the DAQ. It worked. ITDM would like to remove the data. Should be ok.
Due to the triggering of the emergency power off also SPB lost the beam. This was sort of strange since the power off signal was triggered in FXE. AE reported that this behavior is to be expected with the current configuration. This has to be discussed.
FXE
DAQ is recovering from the power off.
Tripping of the interlock caused again by control unit of ion pumps in the week end. During the shutdown the responsible units will be replaced.
In general is is agreed to prepare an overview interlcok panel in the BKR. AE is on boat, CAS to be checked.
500 kHz operation is problematic for the machine due to heavy losses. They are only able to deliver 1 bunch at this rate. FXE will discuss this directly with the PRC (this week is Jan Gruenert)
AE related
Follow up to the issue of re-setting pumps after interlock is triggered: VAC and EPS loops need to be updated. HSinn was pushing to have it done as soon as possible without waiting for the shutdown. This is not riskless for the experiments. This will be discussed in a small round (AE, PRC, SPB, FXE)
ITDM
Due to the power outage many devices do not have proper train id. CAS should check it. Time servers also need to be checked.
FXE needs to use digitizers for the upcoming measurements session. These were not implemented in the DAQ. ITDM/FXE/CAS meeting needed to clarify and solve the issue .
DET
LPD calibration had a problem but should be ok now.
More supermodules coming.
Communication with upcoming userve concerning data format and other issue has to be improved according to the DET group. SPB suggests to tackle the issue offline. |

Gerd Wellenreuther | XHEXP | Problem | FXE emergency power-off has been triggered | Dear all,
apparently the Emergency Power-Off at FXE was triggered at around 10:00 - 10:30 (my estimate). As far as I know power has been switched on again. BKR / PRC have been informed. More information will be provided by TS / Torsten Schön soon.
Edit: T. Schoen is on site and can be contacted under 0160 977 287 97

Adriano Violante | General | Information | Status report after dispatch meeting 09.30 | SPB
On monday there was an issue with a detector related PLC due to misconnection of one EtherCAT cable. The issue has been solved and it "just" resulted in 3 of hours delay in the AGIPD calibration activity.
FXE, SCS, SQS, XPD, XRO,ITDM no issues reported
AE related
uTCA in XTD 6 are installed
VAC-Related
Marc Messerchmidt reported abouit an entry in the DESY Logbook about a pump that triggered the interlock in the SASE1 tunnels. According to Nerea this this seems to be related to the old issue already known. VAC group is working on that.
CAS
CYoungman is working on the priority list for the components in SASE2 tunnels. Double checking with HSinn happening soon.
Access for Tue/Wed next week to XTD1 will be requested by CY through HS
Beam is in SPB/FXE this week due to the HERCULES project. |

Adriano Violante | General | Information | Status and plans after SASE1 Status/SASE3 Readiness Meeting 16.03.. | Photon Run Coordinator (H. Sinn):
1.) SASE1: User experiment SPB could be finished sucussfully after several problems on the weekend (thank to FXE for providing night shift). Big progress in improving throughput of FXE insrument. Next D3 material test with 300 bunches on April 3, 9am.
2.) SASE2: Transmission of electron beam to T5D dump (SASE2 beamline) this week sucessful. Switching between electron beamlines
works nicely (minor problem witth dark current during switching).
Now air coil measurement going on. BBA needs to done before first lasiing starting on May 2nd.
To be clarified today: To we need access to XTD in week 12/13.
3.) SASE3: Photon commissioning (with 24/7 shifts) finished sucessfully. Now specific tasks are done parasitically to SASE1 operation
during regular working hours (organized by photon run coordinator).
4.) General (stimulated by DESY operators): EPS system can lead to shutdown of DESY accelerator through MPS by many different channels (PLC in tunnels, Fast valves, PBLM etc).
On DESY side, MPS provides overview of inputs, but structure difficult to understand and labels are not always conclusive,
On XFEL side, no general overview panel for all SASEs+Instruments (scene) exists, but it required for facility operation.
SPB
No issues/no report
SQS:
- Cleaning of the hutches is ongoing. From 19.3. on, access will be limited. Furthermore, shoe covers have to be worn in E.06 and E.07.
- Electricity in E.22 is delayed. AE and ITDM will be informed about the status by PSPO.
- Vacuum will start the installation of the transfer pipe between the tunnel and E.07 on 19.3.
- SQS will start the installation of their instrumentation on 19.3.
- Some of our beamline components are currently stored at Hera South and must be transported to Schenefeld next week. However, there is an issue with the crane at Hera South. Kai-Erik has to look into this!
FXE (P. Zalden / A. Galler):
No issues/no report
SCS (J.T. Delitz)
No issues/no report
PP-Laser:
"The laser group has nothing particularly noteworthy to report, only that installation is still going as planned"
Vacuuum:
Installations in XTD6 are ongoing. Damaged vacuum pipes have been
exchanged/ordered. Vacuum in XTD1 is closed. Control System in XTD1 is
working and locally tested, Interlock-tests will happen after Easter.
XPD:
No issues/no report
Advanced Electronics:
No issues/no report
SASE2 Tunnels (C. Youngman)
Going according to plan. 1 week after Easter the movement and EPS loops are supposed to be brought up.

Adriano Violante | General | Information | Status report after dispatch meeting 09.30 | SPB (Weinhausen/Round/Mancuso):
- Again on the fast valve was triggering the MPS interlock system. For XRO was not completely clear what happened. for AE everything is clear and it depends on the wrong MPS configuration with respect to missingl cables. The will discuss this offline and eventually bring back the issue. Linked to this, it is reported that the MPS panel is difficult to decipher for the experiments...
- 2 ion pumps went in error and the interlock was triggered. Issue clarified.
SASE2 Tunnels (Youngman)
- Access schedule sorted out. Works in the SASE2 tunnels will be carried out in the period 4-19.04 plus the week before Easter. Discussion with AE on the status of the loops ongoing.
AE (Jardon)
- It is reported by SPB (March Messerschmidt) that people in the BKR are confused about MPS signal that they are getting from XFEL. The different lables assigned to the signals have to be sorted out and communicated. Nerea and Marc will try to start this clarification offiline.
- GATT Loop in SASE3 will be updated today
- Check of the inficon gauges ongoing- eventually update required.
ITDM (Wrona)
- Lots of data (14 Tb) collected during the last SPB shift.
- Issue concerning speed of offline data transfer reported by SPB
- For the user runs in May data will need to be deleted from the offline cluster. A procedure has to be established to clearly communicate with GLs and User groups.
- SASE3 IT installations have been handed over to XFEL. IT setup ongoing. Network will be available in the experiments by the end of the month.

Adriano Violante | General | Information | Status report after dispatch meeting 09.30 | SPB (Weinhausen):
- During the night there was an interlock issue. The fast shutter was triggering the MPS interlock system. After several calls and request of support from SPB to the photon run coordinator and the machine run coordinator the problem was found and the interlock signal bypassed. This was due to some incomplete cabling of the fast valve. While this was knwe, after the last updated the correct configuration was not set up in the controlling PLC.
- In general one has to note that the experiments do not have access to the MPS panels and there is no well established procedure when MPS interlocks are concerned. This will be reported in the PSO meeting.
FXE (Gawelda):
- Before the beam shutdown FXE observed that the beam was very unstable.
- 2 ion pumps went in error and the interlock was triggered. Again in this case is not clear who is responsible for the re setting of the interlock and the pumps.
- Servers had to be restarted due to wrong train id after the cooling water accident
- 0.5 MHz operation of the LPD successfully tested.
SASE2 Tunnels (Youngman)
- It is reported that the technical coordination of the necessary activities is missing.
- A list of activities was sent by CYoungman to TTschentscher concerning SASE2 tunnels. In total 10 working days are needed to complete these tasks. This includes 1 week implementation and 1 week commissioning. Carefully planning with DESY is needed to avoid that the necessary 10 working days are scheduled around Easter, which will result in less effective days.
CAS (Santos)
- HSantos is preparing a deployment plan for Karabo whoch includes the requirements and deadlines to be fulfilled by the other support groups (ITDM, DET, AE). The idea is to have this plan presented on Friday for discussion.

Adriano Violante | General | Information | Status and plans after SASE1 Status/SASE3 Readiness Meeting 09.03 | Photon Run Coordinator (L. Samoylova):
Commissioning during machine studies Tue and Wed and parasitically during SA1 user operation at
SASE3 on Thursday and Friday
SASE1
SPB
User operation, current status (Adrian): got few data from a test system on Saturday. The users’
sample delivery technology now seems to deliver nice & stable droplets, so if SPB
get beam early enough today to set up for a measurement, a full data set could be collected.
FXE
- Instrument Commissioning
- Measure beamline transmission (unfocused 550 µJ per pulse at the sample position, with lenses
115 uJ)
Machine studies
- Wed afternoon: a set of K-mono FEL spectra taken
https://ttfinfo.desy.de/XFELelog/show.jsp?dir=/2018/10/07.03_a&pos=2018-03-09T17:56:20
SASE3
Thu, Friday - a first experience of the SASE3 commissioning in 30 bunch mode during user operation:
- minimal number of undulators (12) for lasing, low intense SASE (XGM shows 10 uJ, linear
regime), SRA closed to 2 mm
- MCP2 @ SASE3 - signal from 30 SASE pulses, consistently decrease with closing the slit down
to 0.5 mm
https://ttfinfo.desy.de/elog/XMLlist?file=/XFELelog/data/2018/10/08.03_a&xsl=/elogbook/xsl/elog.xsl&picture=true#2018-03-08T18:24:14
Problems:
'unexpected' from photon side closing XTD1 two working days earlier, explicit schedule
- for the south branch tunnels access would be appreciated
- power off in XHPSC on Thursday at 21:15, no cooling water in experimental hall that led to
increasing the temperature in the rack with the MicorTCA crate, the CPUs of the two MicroTCA
crates in SPB and one of the two crates in FXE were automatically switched off. SPB crate
1 did not come automatically back afterwards, as the result: no train IDs for SPB PLC
loops, no MPS for SPB, no Clock and Control for AGIPD, no triggers for SPB systems on
Friday
- Saturday morning the MPS interlock takes into account the signal from one of three fast valve
on SPB shutter although these valves are disconnected to SPB EPS interlock. The MPS
bit had to be masked
Correction from SPB [12.03.2018 10:10]: This issue was not related to the XTD9 shutter, but to the
optics hutch shutter. The fast valve in XTD9 is connected to the EPS, the fast valve
in the OH is not yet connected to the EPS. After the restart of the EPS/MPS on Thursday
/ Friday after the cooling water issue, the condition for the fast valve in the optics
hutch was wrongly included in the MPS.
SPB
1) Thursday 08.03.2018 (8 am - 8 pm) - SPB/SFX commisioning shift
Notes:
- everything running
- RAW data overview very responsive with data filtering as suggested by Steffen
- Corrected data preview started very nicely and seem to provide only limited update rate after a few hours running
- karabo DAQ deices (dataaggregators) need several rests, resulting in a full DAQ restart around 7pm
- sometimes updates in KARABO were lost
- preparation for users experiment - over night
2) Thursday 08.03.2018 (around 9 pm) - "cooling water" incident
Notes:
- vacuum pumps affected
- AGIPD warmed up
- uTCAs have tripped/shutdown (some infrastructure needs to replaced)
3) Friday 09.03.2018 - morning (User beamtime)
- damaged uTCAs equipment was replaced but trigger setting needs to be input/ adjusted = loss of the user beamtime
- User experiment progresses
SQS:
Hutch cleaning Mid. March
KB tanks installation in parallel with SCS
9-14 air filter will be installed. After that date only clean works have to be carried out
Collision with KB tanks installation and other activities like Rad. Interlock test to verify
FXE (P. Zalden / A. Galler):
Setting up the experiment
IPM and XGM data manualy correlated. Would be nice to have the train id working to have the "live" correlation
SCS (J.T. Delitz)
- cleaning of hutch next week (wk11)
- we will start moving first components wk12-13, ie. ALAS and DPS
- KB installation (positioning only, no AC+filter required) beginning April-depends on commissioning of precision climate zone (currently discussed with PI)
PP-Laser (M. Lederer):
SASE1 commisisonin gonoing.
Some misalignment due to the cooling water accident. To be investigated
09.04 SASE2/3 laser tables will be installed.
Vacuuum (R. Villanueva):
SASE2--------->Good progresses on XTD1 control system deployment: Differential Pumping sectors are ready for first beam // First five vacuum sectors under vacuum and locally tested (already with Karabo). XTD6 tunnel installation phase progresses at good pace.
SASE1--------->In general, nothing additional to remark. We are working in a more robust interlock definition to prevent false triggering due of ion pump control signals.
SASE3--------->Complete vacuum system is working normally. Gas Attenuator is now under routinary operation up to 2-3 mbar with a UHV interface pressure after its DPS sector < 1*10e-9 mbar.
XRO
SQS/SCS/XRO collaboration for the mirror coating ongoing
Installation of M5 in preparation
XPD (T. Maltezopoulos ):
XGM@XTD2, @XTD9, and @XTD10 are online.
XGM@XTD1 is in the loop and accessible from Karabo
(together with AE+CAS).
Currently I test XGM@XTD1 components from DOOCS.
XGM@XTD9 shows slightly higher energy then in XTD2.
I calibrate all XGM components twice, but still it remained.
Note that the beam pass the XTD9 XGM with -7 mm offset
(in beam direction 7 mm to the left, to the south).
With this high offset absolute calibration is not guaranteed.
Advanced Electronics (P. Gessler):
1 CPU for SPB broken due to the cooling water accident. Already replaced. Being configured
FXE grating integrated in the vac loop
SASE2 Tunnels (C. Youngman)
More coordination is needed, especially concerning the access to the tunnels. For the technical details, please see slides on the indico page https://indico.desy.de/indico/event/20115/
ITDM (K. Wrona):
No problems with overrheating
Problems with Train ID reliability after the heating. Should be checked and monitored online
Documentation of single devices have to be improved. + there is need for a tool to make the sanity check
Detectors (J. Sztuk-Dambietz, P. Lang):
LPD commissioning OK + DAQ working. Now LPD off because of cooling water problems.
CAS (H. Santos):
- Sandor is in a meeting with the Detector group to align requirements regarding AGIPD and DA
- We started to prioritize and address the (agile) missions of SPB and FXE. As part of this effort:
- Alessandro started to develop the scenes link on the GUI. This feature is really required and has been present in several SRDs (For example, to link vac sections/loops).
- We implemented the GUI combo box to select different GUI Server - it is part of the SPB Mission (Leonce)
- Hamed and Sergey made good progress on the Digitizer. They will work on a demo/talk for the next PBS Meeting.
- Wajid, Sergey, and Dennis fixed the X2Timer issue reported by FXE (hash/data inconsistency). It is already deployed and running.
- Regarding the cooling incident. Wajid was the first contacted yesterday. After that Alessandro at 01:00. Today, during the morning, we reinstall Karabo at SPB-RR-SYS-UTC-1.

Adriano Violante | General | Information | Status report after dispatch meeting 09.30 | SPB:
- Monday morning Karabo failed. It was not possible to operate anything. Aftrer restart it took 2 hrs. to have the tunnel loop and Lopp 5 again operable . Other issues connected to that. CAS is on it.
- AGIPD can be operated with some workaroung concerning the control system. No final fix available yet.
- CSS can be operated locally.
- Coordinated motion test probably on 14.03.
FXE:
- IPM/XGM correlation data process ongoing.
- DAQ worked reliably
- Scan tool operational for almost every component. Data storage works. Test ongoing.
- PG points aout that no MPS definitions were given and no MPS is available for FXE yet. To be checked.
SQS
- Corrdination of installations in the hutch with the TUV tests for Rad. Interlock needed.
SCS
ITDM:
- FXE LPD slow data separation will be done today after the meeting
- Some devices are setting the train id as "0". CAS is informed.
SASE3
MCP HV - Crate restarted. Now ok. There was a misconfiguration of Power/Karabo settings. This meeds to be avoided increasing the communication between people performin operations on the XPD components and the technical support groups.
AE
- uTCA crate in SASE2 for timing being prepared, as well as PLC for VAC loop
- Replacement of a uTCA crate in the balcony room for SASE2 needed

Adriano Violante | General | Information | Details on SPB issues reported in the dispatch meetings | Below some clarifications from R. Bean on the issues reported in today's dispatch meeting:
- AGIPD suffered many problems which affected the operability (not really a problem of the scene). It was just operable, although not at all efficiently. Problems with the pipeline / DAQ and Karabo controls for the AGIPD suggest that some reasonable amount of work is required to find and solve the problems which may not be independent from each other
- CAS OCD point already addressed with previous email: They were available, just we needed them rather more than we should have done
- The CSS is the large rail that carries the detector. We cannot move it via the integrated system because of a misunderstanding in the implementation of limit / safety switches into the eplan design of the crate. The cabling between rack room / device seems to be fine (but of course not really tested properly because the crate is not correct). We have to use the test crate to move it right now, which is rather tedious since the encoders / limits cannot be handled properly by that system. I am available to discuss the proper implementation of switches / buttons such that we don’t need a fourth attempt at this crate
- For the smaracts we still have axes that are not controllable via the PLC. It is these that would be beneficial if they are fully integrated |

Adriano Violante | XHEXP | Information | Status report after dispatch meeting 09.30 |
SPB
- Last night the beam disappeared between 4 and 8.
- AGIPD scene showed many problems, both concerning Karabo and Data preview. Detector is not operable. To solve the issue a joint effort of all the groups involved, as well as the physical presence of experts during the shift is requested.
- CSS has to be moved out of the beam. As of now there are problems with cabling that need to be solved
- Smaract stages are misbehaving. More support from AE (Mahadi) is requested
- Status of the coordinated motion test was asked. Should be ongoing but the experts were not there.
FXE:
- Testing fast intensity monitors and LPD
- DAQ worked very well
- Scan tool must me tested
- Correlation between LPD and fast intensity monitor is problematic due to train id problems. There is a new device to be deloyed on the XGM. Today or tomorrow will be seen whether this solves the issues.
- BKR reported that the beam tripping was due to some FXE device close to the M3, but FXE is not aware of that. Info will be asked to Harald today during the PSO meeting.
Advanced Electronics (P. Gessler):
- MCP HV problem in SASE3 - the power supply failed. The fixing shoud be done according to the priorities, Photon run coordinator decides.
ITDM (K. Wrona):
- FXE slow data DAQ issues: these will be solved splitting the LPD slow data from the rest. small update of the software needed.
- Simultaneous acquisition from LPD and cameras is now available and working well.
Detectors (J. Sztuk-Dambietz, P. Lang):
- AGIPD will operate with the old firmware due to problems with the new one
- No calibration data available as of today
- AGIPD is in a safe state

- Radiation tests done
SCS (J.T. Delitz)
-
Removing of wood cover: 05.02.2018
-
Cleaning: end of week 11.
-
End of march beginning of the installation of the first components (ALAS and TIM)
-
Waiting of the exact date for Interlock test to specify more exact the dates for the KB mirror system installation.
PP-Laser (M. Lederer):
Vacuuum (R. Villanueva):
- SASE1
- Nothing remarkable: the whole vacuum system works in a very stable way. We only had one incident on the output of 1-2 ion pumps that trigger once the interlock. For that we are investigating the causes .
- SASE 3.
- The whole vacuum loop (as required for the first lasing) down to the instrument front-end is under control and no special issues have appeared yet.
- The SASE3 Gas Attenuator is under manually operation and most of the Photon Commissioning Members are familiar with it. Next steps are aligned with the deployment of the Pressure Feedback Control PID control available at Karabo level and to continue with the software-related tasks.
- SASE2.
- XTD1------->The complete vacuum string down to the front-end in the shaft building is under vacuum but in local mode operation (including XGM subsystem)
- ------->During this almost past week we already initiated the PLC local tests (i.e. US & DS Differential Pumping are already done), and in KW10 we aim to move on with the rest of the system (ion pumps and vacuum sector gate valves).
- ------->Absorber, V0 and Fast Valve wiring are in good progress and we think they could be ready for local tests by the beginning of next week.
- ------->The interlock tests are planned also for KW10.
- ------->Depending of the progresses of AE and CAS, we may even be able to deploy the first control scenes in Karabo.
-
- XTD6 ------->The assembly works of the whole beamline there progress adequately and without remarkable "show-stoppers" that couldn´t be managed.
- ------->Vacuum Group and Optics group (N. Kohlstrunk) are having also special attention and dedication to the SDU vacuum chamber conditioning and preparation works for its upcoming in-vacuum mechanics installation.
XPD (T. Maltezopoulos ):
- XGM in XTD1 is connected to DOOCS (together with DESY)
- Synchronization of XGM@XTD1 microTCA next week
- Local tests at XTD1 XGM were finished (together with AE)
- XTD2, XTD9, and XTD10 XGMs are running 24/7
- Change to 300 bunches went without problems
- XTD9 XGM need SRG recalibration ... done meanwhile
- Wajid, Joakim, Tommaso, and Theo will repeat SASE3 DAQ Imager/XGM correlation today (need single shot operation)
Advanced Electronics (P. Gessler):
- Broken terminal between SASE3 MOV2 PLC Loop and Master Loop were replaced last Friday without any side effects. The Train ID is now also provided from the MOV2 loop.
- So far, no PLC related export from the SASE2 Tunnel eplans of the vacuum, beam transport and diagnostics PLC crates are possible. Therefore we will build up the XLS file for the start up of the VAC and XGM loops next week. However, the related group plus AE and EETF should meet to evaluate, if an export is possible until end of March in order to use it for further installation work. Otherwise XLS files have to be crates manually again with support from all involved groups. Also consistent documentation is required between diagnostics on one side and vacuum and beam transport eplans.
SASE2 Tunnels (C. Youngman)
- Table with the set priorities and deadlines available in Indico.
ITDM (K. Wrona):
- Run Configuration Groups required for the user experiments for FXE and SPB/SFX have been defined and tested
- Discussion after the meeting: Since the Karabo-DOOCS interface for XGM will be changed and it will affect also how the data arrive at DAQ data aggregators we need to modify and (re)test the BEAM_COND group.
Detectors (J. Sztuk-Dambietz, P. Lang):
- AGIPD will operate with the old firmware due to problems with the new one
- No calibration data available as of today
- AGIPD is in a safe state
CAS (S. Brockhauser):
- Gotthard for HIREX being operated
- Progress on GATT commissioning by Valerii

Adriano Violante | General | Information | Status report after dispatch meeting 09.30 | SPB:
- Ion pumps running in the Mirror chamber. Vacuum level OK to run.
- D.02 is now interlocked and is a clean area.
- Mahadi and Alessandro are setting up a test system for the coupled movement. The test will probably be done between the 2 users periods.
- 2 hours of parasitic beam can be used today to check the alignment of the CRLs. The CRLs will be then moved out of the beam to allow the FXE radiation tests tomorrow.
- Primary limits for coupled motion not included in E-plan, safety switches are implemented but SPB prefers to have the primary limits included. CSS crate to be modified after clarification with AE/EET.
- Test of the karabo brigde will be performed with users. It is not yet clear exactly when since this needs synchronization with several groups involved (CAS, ITDM, DET).
FXE:
- Radiation test tomorrow
- LPD test measurements in thhe WE
- Von Hamos spectrometer alignment until monday
ITDM:
- SASE1 and 3 have the last DAQ update now. Stable in SASE1 so far.
- Data sources arrangement being worked out. Today a 45 min session is foreseen with SPB.
- SPB needs slow data acquisition from 2 cameras for users, apart from AGIPD.

- Ion pumps running in the Mirror chamber.
- Starting test with mirrors together with CAS this week.
- In general everything in good position to receive beam.
- Primary limits for coupled motion not included in E-plan, safety switches are implemented but SPB prefers to have the primary limits included. This will suppose a hardware modification.
AE:
- SASE3: train IDs in loop2 are working, the problem was fixed last Friday.
ITDM:
- Measurements for commissioning continues.
CAS:
- H.Santos inform that CAS has not resources to run tasks for SASE2, this might affect the date for first lasing in SASE2. Priorities are SASE1 operation and SASE3 commissioning.

XPD (J. Grünert):
XGM SASE3
- tuesday XPD made XTD10 access to repair SASE3 XGM vacuum
- one turbo pump failed Saturday noon, decided to repair during access tuesday, exchanged pump
- tuesday detected another vacuum trip in the differential pumping around the XGM
- wednesday afternoon VAC made ZZ-access to „repair“ what tripped the vacuum interlock
- wednesday to thursday night: checking proper and stable SASE3 vacuum operation - is ok
- XGM is back in operation since thursday morning 8am
XGM status overall:
- XTD2 and XTD10 XGMs in operation
- When will the XGM in XTD9 be needed? ==> Harald and Liuba believe that beam might be sent to XTD9 this weekend, therefore they request to start XTD9 operation today afternoon
Imagers
- SQS Exit slit imager has been set to beam position and can be used for some basic commissioning (limited functionality)
thursday work with beam:
- SASE1 KMONO studies: two cells studies, height adjustment of single cells using DAQ (until it crashed at noon), data analysis today
- HIREX commissioning
- SASE1 beam conditions recorded with DAQ
Correlation of beam intensity monitored by XGM and imagers

- Request to CAS:
- DOOCS devices shall be created for SASE3 (as in SASE1) for undulator and phase shifter and electron beam energy
Advanced Electronics (P. Gessler):
- SASE3: No train IDs are being delivered in loop 2. Repair could potentially / in the worst case affect all electronics. ==> Should be fixed right now to get it done.
ITDM (K. Wrona):

- We released Karabo Hotfix 2.2.2.2 to fix an issue on the RunConfiguratorGroup at SA1 (ITDM already checked and it is working)
- We have improved the communication protocol with AE on handling loops/PLC updates and related (re)establishment of the Karabo services.
- AGIPD library is extended to supply information if detector is in stop or acquire state. The next step will add the "acquisition time" to enable scantool integration
- The old digitizer is running and integrated with DAQ. Also, we will add the "acquisition time" to enable scantool integration
- We started to call the Sprint Meetings (for the moment we focus on updating the priorities of FXE and SPB topics)
- A list of 'potential' SA3 technical coordingation activities was sent to the 'Photon run coordinators' and PSPO listing what technical coordination tasks can be done parasitically during access period.
- The SA2 technical coordination planning has started initially with the front line groups: ITDM, AE, VAC, then Beam transport.
- ITDM have nearly finished the server installation (same as SA3), AE have responded with loop and MTCA plans
- VAC and Beam Transport have so far not confirmed their meetings for this task
AoB:
E. Boyd: A test @ FXE with Cu-Target and 300 bunches is required. This will affect the areas / hutches around FXE
A. Mancuso: Will try to work around this, but in general a message one week beforehand would be required / appreciated. |

Alessandro Silenzi | General | Information | Re: Status report after dispatch meeting 09.30 | Small correction:
The coordinated motion is the KB-mirror's, not the Vacuum.
The postfix is 2.2.2.1 and includes features that were not included in 2.2.2
Karabo 2.2.2 is ready
