- Test of the mirrors movements is done.
- Mirrors cooling bars being installed
Vacuum
XPD
- Pop-in monitor filters in XTD10 being changed
- Exit slit imager after Mono XTD10 has ot be commissioned and scintillator has to be put out of the beam way.
AE
- It can happena that some parameters cannot be set using Karabo due to lack of writing rights. A fix has been found but we would need to update all the loops. Since the problem is just occurring from time to time, AE asks to report specific cases for whoch a solution will be found. Same things happens with the re initialization of some devices. In this case the PLC crashes.
- Timing device in XTD 2 stopped working. Will be fixed today either by remote re start or by local intervention.
ITDM
- Broken server replaced
- Tomorrow there will be an update of the cluster between 9:00 and 10:00. DAQ will be down.
- Reboot of the online cluster needed. To be agreed with Detector group. 1 hour downtime also in this case.
CAS
- In SASE3, deployment of new (2.2.1) Karabo happened yesterday and seems stable, but brittle. Analysis of the reason ongoing.

CAS
Report of the XTD10 interventions from last week - Tuesday and Wednesday - C. Youngman
Many thanks to those who contribute to the "SA3 'further technical coordination push" onTuesday (no-beam XTD10 closed) and Wednesday (XTD10 open) mini-shutdown, below is brief summary. The status items were not highlighted during PSPO's readiness meeting AoB section but are useful to know. Those issues that were raised are contained in the conclusion section.
We leave the SA3 beamline with a functioning interlock, but you should additionally watch and test your component and ensure that beam operation is possible.
The principle task on Tuesday was
- for ITDM to shutdown and update f/w of the control server CPU hosts in the balcony room, and
- for CAS to replace the Karabo 2.1.18, running since the Oct-Nov shutdown 2017, with Karabo 2.2.1 which is already running on the SA1 installation.
- A number of problems during the installation were addressed and a stable deployment was finally reached early in the evening.
The principle task on Wednesday were
- test the updated GATT Ebara pump updated f/w and its s/w counterpart
- test that GATT Bronkhorst Mass-Flow valve f/w worked: correcting conversion errors and the incorrect setting of property r/w attributes
- test that GATT Inficon gauge f/w did not crash the loop and correct conversion and r/w errors as with the the Mass-Flow valves
- perform Beckhoff-local tests on one or more the DOD motor axes as they were expected to be wrongly wired (as seen in the Jan-Dec shutdown in the VSLIT)
- update the s/w to reflect changes in the GATT f/w
- address difference in the s/w introduced by the move to Karabo 2.2.1
The key-point task listed above have been attained with the following caveats:
- There is a h/w fault which prevents the second Ebara pump being fully controllable remotely, it is currently locally controlled.
- Bronkhorst f/w and s/w is usable, the conversion is correct, but additional s/w work is required to align the s/w
- The Inficon f/w works (it does not crash the loop), the f/w conversion error is identified but not enough time was available to modify it.
- some s/w issues remain which are being addressed (tagging of Ebara, Bronkhorst and Inficon s/w, correct configuration of the vacuum-section..)
- the automatic update of project and scenes was not completely successful so project and scene owners should check and correct their scenes. The auto update procedure will be improved.
- Some data logging information was lost, but e now have regained a standard implementation (not hot-fixed) which should improve the this.
- After measuring that the DOD axes (1 of 10) were incorrectly wired it was concluded that all were incorrectly wired (as had been the VSLIT in the Dec-Jan shutdown)
- Benoit and Daniele managed to rewire all 10 DOD axes during the mini shutdown and test 1 axis with Karabo.
- PES tests of multi-board digitizer s/w and f/w were continued (with measurements at the crate), these are promising as 'raw' and 'processed' data are now concurrently available.
In conclusion - good progress was made and this type of 'commissioning' mini-shutdown (anything longer than ~4 hours which includes somebody elses longer ZZ) should be performed as often as possible.
This requires
- that the photon run coordinator team know that there is a "list of task" to be performed which are not in the ZZ list
- that a selection of these tasks can be performed within the time budget of a mini-shutdown and that these do not compromise SA3 tunnel operation
- that the photon run coordinators inform the SA3 technical commissioning team (contact a member of the "SA3 tech coord" CAS team setup by Sandor, e.g. Chris, Valerii or Wajid ) so that they can organize the work in time (or report that they cannot as something or someone is not available).
During the next few days a "list-of-task" will be created. This could include technical commissioning actions for SA3: PBLM, ExitSlits, very end of beamline imagers where the status needs updating, etc.
Also remember that the CAS team tries hard to satisfy as many requests as possible, but prioritization will be done, so make your case thoroughly and don't expect it to simply happen (it has to be on the radar screen). In particular h/w, f/w and related s/w tests needing access will be done first and non-critical s/w work will be left until after tunnel closure. And remember to check your projects, scenes, and macros before you need them.

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.
VAC/Detector/XPD/CAS: nobody attended |

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

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 | 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.

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.

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

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. |

- Digitizers were already implemented in the DAQ but there is an issue related to the Karabo device. CAS already looking into that.
AE
- Follow up to the issue of re-setting pumps after interlock is triggered: loops updated.
- SASE2 MOV loop patched
- Imagers in XTD1 have to be tested with Karabo
ITDM
- On monday afternoon problems with the storage servers were reported. The issue is a defective board, whoch is meanwhile been deactivated. IBM is working on that. The system seems to be working in this state.
CAS
- The next Karabo release will be able to handle better big loops. ASilenzi points out that the next update is really important since it adresses problems like the restart of time servers issue.

SPB
- After re-compiling the relative karabo device, the configuration procedure of the AGIPD is now smoothand reliable.
- PLCs update ongoing. AGIPD is in a safe state to allow the PLC update.
SQS
- Meeting today at 11:00 with AE, EET, CAS to define the next steps of the end to end tests.
AE
- SASE2 tunnels - Only VAC conditions are transmitted from the EPS loop to the MPS. All the other conditions were supposed to be not necessary for first lasing and were not implemented. Nevertheless this was not clear for the people working in the BKR (especcially for diagnostics) during the last days. It has to be discussed with the PRC (H. Sinn this week) whether these have to be implemented on a short time. In pronciple AE can do it if requested. Otherwise the definitions will be implemented in the next shutdown.
ITDM
- Failure of one IBM server for online storage. Thanks to the implemented redundancy this will not affect the operation. The performances have to be checked. IBM has been contacted.
- On monday evening ITDM OCD received a call from BKR because of some problems with the DAQ in the tunnels. It seems that this was due to the fact that the system was not properly tested by the "users" before. Seems to be solved now.

General
- For the upcoming emergency off test in SASE1 SPB and FXE should propose a possible date in the next shutdown to be then discussed with AE.
- The machine is down due to the failure of a cryocompressor. Beam will be probably coming back tomorrow morning. Tomorrow morning will be also confirmed whether SPB and FXE cold use the beamtime for the user run.
SPB
- In the week end there was a failure of the PP laser shutter. It was possible to find a very temporary solution to circumvent the problem.
- The beam has been unstable for most of the time. No drift, mostly gitter. Reasons are unclear. The instability was also measured with the XGM in XTD2. SPB is analysing the data collected to be able to quantify the instability.
- DAQ tests for AGIPD were planned for tomorrow but the request is to shift them to today to take advantage of the missing beam.
FXE
Some issues were reported: LPD readout of the data, Fast digitizers mainly. The details have to be clarified with the DET and ITDM groups.
AE
SQS loop 3 is up and running.
