Dear all,

I updated the tunnel access schedule to reflect the access to the XTDs tomorrow.

Cheers, Gerd

Dear all,

XTD9 will be accessible tomorrow until the afternoon, but access should be communicated to M. Dommach, H. Sinn and T. Tschentscher. Martin will organize a search team for the afternoon.

Cheers, Gerd

General

• First users have done experiments - despite the current problems it appears as if everybody was able to take some data for future publications.

Short Report from SASE1 Instruments

• ​SPB (A. Mancuso): 
  • ​Beam was lost due to incident with electron beam hitting & damaging components downstream of the northern dump.
  • Currently only single bunch operation
  • Lots of work to be done in Oct. shutdown, Adrian will provide a list to Thomas Tschentscher
• FXE (T. Tschentscher):
  • ​Problem with the Tangerine-laser affects PP-experiment ==> to be fixed on Tuesday
  • Consider to switch to oscillator only until then ==> lower repetition rate, lower OL pulse energy
  • Next experiments require Gotthard & LPD in parallel operation ==> merge Gotthard & LPD to same run control next week before user run.
  • Today, test with DAQ and Gotthard was successful, but Gotthard has never seen XFEL X-rays so far. ==> Test with beam could happen potentially Monday night (instead of user experiment)

Tunnels (M. Dommach, J. Grünert):

• SASE1:
  • Few issues with XGM, have been or are being solved.
  • It was suggested to put the Hirex-grating into the beam while FXE is taking beam to measure / commission parasitically. But it appears next week neither Naresh nor Jan will be available.
• SASE3:
  • ​Due to the electron beam incident the first vacuum sections have been vented, there is most probably a hole in the V0, but only Rad. Safety to access the tunnels right now. ZZ/Access by anyone else only after clearance through SRP - working there is probably only possible in Octorb
  • Beam did hit the beam pipe apparently just upstream of the transmissive imager. Imager and further (vacuum) electronics seems to have been damaged in the upstream part of XTD10.
  • Due to this incident, it should be reconsidered if dosimeters are required in XTD10, too. SRP did unfortunately not participate, and thus was not able to comment.

Laser

• Working still on improving the laser
• Issue regarding motors coming back to their position is most probably a firmware/options issue

Detectors

• AGIPD:
  • ​According to Yolanta "operates better than expected"
• LPD
  • ​Also operates better than expected
  • Configuration of LPD is getting messed up by people working in parallel / unclear status of the detectors Gotthard & LPD ==> There should be a responsible for the detector, who is present in the control room and can allow remote access to work with the detectors / run configuration. ==> These steps should be well-documented in the FXE-Logbook.
  • K. Wrona: Next week will be better with just one run controller.

Electronics (P. Gessler)

• There is an issue with some motors & encoder @ SPB.
• AE will finish the work on the last loops in SASE1.
• WP79 needed & got support by AE.

ITDM (K. Wrona)

• DAQ for the tunnels is setup. ==> XGM-run control for the tunnel is to be tried.
• Slow data: It is an issue how and how fast to store slow data (lots of properties which do not change).

Software

• FXE:
  • Still daily meetings, prepare LPD & Gotthard
  • Working on GreatEyes, too
• SPB
  • Configure slow-data cameras
  • Laser project is running in CAS
• SASE3:
  • C. Youngman is the CAS-responsible, should collect requirements to compile master equipment list for SASE3 ==> to be compared against MEL SASE1 to identify additional work required.
• SASE1:
  • Loops & Karabo will be updated together.

October Shutdown:

• SASE1
  • No major items here currently, focus is on SASE3 / XTD10.
• SASE3
  • First priority is to get all items required for first lasing up & running ==> Vacuum system including anything up to the absorber.
  • CAS is starting to set up Karabo and all controls.
  • ITDM will also start to work, but does not require access to the tunnel.
  • C. Youngman to generate MEL from input from the groups ==> invites to a meeting if necessary.
  • Eplan for PES will not be available on time ==> has to be pumped in a provisional fashion.

SPB (A. Mancuso): 

• ​Users are in good shape
• Beam operation with ca. 600 microJ, but beam seems to be ring-shaped after M2?
• Preparing for first pump&probe experiments in November.
• Start of the focussing mirror controls should start after the user run

FXE ():

• ​Was not present at the beginning of the meeting, so nothing was reported.

Tunnels (M. Dommach):

• SASE1:
  • Nothing particular.
• SASE3:
  • ​Preparing for the works in XTD10 during the Oct. shutdown are ongoing.
  • PES: Will just be connected to vacuum & pumped, not functional.

Laser (M. Lederer)

• Sustained small damage during set-up
• Not much time left until user run requires PP-laser
• Issue regarding motors not coming back to their position reliably still persists / is not solved. ==> To be tackled by Gabriele (CAS) + Nerea / Nicola / Janna (AE)

Detectors (P. Lang)

• Detectors are in operation
• Works in Oct. shutdown mostly indepenent from other groups
• LPD & Gotthard run together, but Gotthard has not yet detected X-rays?

Electronics (P. Gessler)

• Preparing for Oct. shutdown
• Train-builder should be tested in the Winter shutdown, because the contract only runs until March.

ITDM (K. Wrona)

•  There are some issues with run-control, being investigated.

Software (S. Brockhauser):

• Daily meetings with FXE & SPB.
• C. Youngman is working on the Master Equipment List for SASE3. The basic assumption is to copy any configurations/parameters from SASE1 to SASE3.
• Focussing now more on the SASE1-issues (e.g. Karabo-DOOCS-Interface ==> will mirror devices from Karabo into DOOCS.)

Priorities & Schedule (T. Tschentscher, G. Wellenreuther):

• Performance of SASE1 has to be improved, in particular the performance of the accelerator. This has higher priority than continuing building up SASE3 or SASE2.
• For example, the measurement of gain curves requires the MCP, consequently its completion has highest priority.
• The control room also needs fast & direct access to more devices than just the XGM to properly tune lasing, consequently the Karabo-DOOCS interface has highest priority.
• For the overall planning of the next ca. 5 weeks all groups are expected to report back to T. Tschentscher & PSPO until Wednesday next week. PSPO will produce a Gantt-chart of all activities. Template for the feedback will be sent around still today.
• PSPO is tracking ALL major activities associated in all SASEs in the presentation shown. Missing items to be reported to G. Wellenreuther. Will be revisited on a ca. monthly timescale
• Planning for the next shutdown in December should commence in early November (= after the upcoming shutdown), to allow for proper planning and preparations.
• Despite the priority on SASE1, activities in SASE3 and SASE2 should progress. We still would like to attempt to do first lasing in SASE3 before the November user run!

SPB (B. Weinhausen): 

• ​Users took good data
• Problems occured with the DAQ / control system
• Working on diamond @ beamstop
• Preparation for several updates / activities regarding AGIPD

FXE (A. Galler):

• ​User took good data, analysis is ongoing
• Will rework cable routing/connections
• Chiller was moved to the rackroom, redo the connections etc.

Tunnels (M. Dommach, H. Sinn, J. Gruenert)

• SASE3:
  • ​1st section is not recovered yet, DESY Vacuum has to replace the last valve here, works have not started yet
  • 2nd section with K-Mono, which was vented, is now pumped again.
  • Diff. pumping in gas section has been tested, upcoming are interlock tests
  • Gas attenuator still needs a lot of cabling, cooling water and compressed air
  • Leak test starts
  • MCP has to be connected next week
  • Leak @ absorber: has to be reweld by Trinos, or a blind flange has to put right after the absorber ==> should not hinder the 1st lasing attempt.
  • Absorber was moved ==> has to be realigned by MEA
  • A. Koch is ready to commission several imagers as soon as the motion loop is up&running
  • Next Monday AE, WP74, Vacuum etc. will finalize which components will be implemented in the motion loop during the October shutdown
  • MCP, FEL-Imager: Crates are there, AE still has to understand and define the priorities of their work
  • Repair of MCP: Access to XTD required, WP74 to clarify with SRP.
  • No access to the tunnels with visitor cards! (Access to tunnels requires rebreather training, knowledge about procedures, warnings, dosimetry etc.)
  • Hirex was calibrated @ 9keV, is ready to measure the bandwidth, was determined to be 20eV FWHM

Laser (M. Lederer)

• NOPA-Alignment progressing
• Some setbacks due to shutdown activities by MKK, which affected the humidity stability ==> tables bend
• Laser synchronization has to be implemented by WP18, is questionable, the responsible expert is going on vacation next Friday.
• Motors seem to move reliably now
• No process yet to let the users easily change the laser burst pattern via software. Currently, BKR is being informed about our needs, and they "drive" the laser through timing signals from BKR.
• Laser group will operate in a shift pattern:
  • 8-16h morning shift
  • 15-23h late shift

Detectors (M. Kuster)

• AGIPD:
  • Decided not to modify the vacuum
  • Working on internal calibration
  • Working on increase of the bias voltage to improve the performance
  • Electronics are being replaced partly
• LPD:
  • Upgraded the chiller
  • A leak occured due to the increased pressure, since the chiller was put into the rack room ==> pressure reducer is used now
  • Will exchange faulty super-modules
  • Working on the internal calibration
• Planning next beamtime & shift schedule as laser group has setup
• There still exists a risk to collide AGIPD-modules, meeting with the AGIPD-consortium to agree on changes for the next detectors
• Problem with additional frames which had to be taken during data acquisition: pattern upgrade / firmware upgrade required, will not come in October.

Electronics (P. Gessler)

• Responsibles
  • SASE1: Bernard Baranasic
  • SASE3: Jan Tolkiehn
  • Instruments SASE1: Tobias Freyermuth
• Lots of updates are required, could all be done in short succession ==> can the beamline be put in an insensitive state, to allow quick series of updates?
• Documentation by WP74 + Vacuum is not consistent ==> AE will provide an Excel-sheet to be used, which should give a consistent picture of all terminals, connections etc.

ITDM (K. Wrona)

• Both online & offline-filesystems have to be updated. Monday: Online-FS will be down, offline-FS will be worked on continuously, should not be down, but at reduced performance, since update will be server by server.
• How should ITDM communicate this to the user? Suggestion: Setup an email-list for users to subscribe to, so those individuals who actually work on the data get the updates, and not every user.
• Capacity of the offline FS has to be increased
• DAQ-Upgrade: still running Karabo 2.1.12 on detectors, which requires lots of restarts. Will upgrade to .13 first.
• Still there is no proper commissioning of the Gotthard. Testing would be appreciated to improve reliability ==> time required from Detector and Instrument

Software (S. Brockhauser):

• Karabo 2.1.18 to be released today, but not immediately to be installed. To be deployed after PLC upgrades.
• Karabo + DOOCS: A meeting took place with T. Wilksen (responsible for DOOCS). ==> interface for slow data / digits exists, but not for pipelined data / cameras / images
• Highest priority of the DOOCS-Team are the SASE3 undulators, which is not in line with the XFEL priorities (improving the stability / reliability of the SASE1 operation)
• C. Youngman to work on the master equipment list for SASE3
• A. Galler: Is the current situation really bearable for the instruments, can we actually call this upcoming beamtime "user time"? ==> S.Brockhauser: Lots of problems have been solved, new will arise...
• A. Galler: Will we be able to do a simple blade scan through a laser beam and get a plot?
  ==> S. Brockhauser: We are working on this. You can have plots showing motor positions, intensity, and then correlate this.
• H. Sinn: Basically, we still to not have a working scan tool, which is a big drawback. This is one of the very basic functionality every user will expect!

Priorities & Schedule (G. Wellenreuther, H.Sinn):

• Operation board should decide about updated schedule next week
• Users & instruments request time to with beam to set up before user time!
• OCD-contacts for TS were provided (again?)
• In general, interface to OCD should be harmonized for all groups (e.g. always have a fixed cellphone number)
• Activities for the shutdown have been gathered by PSPO, and are being provided to the support groups for crosschecking.
• No major collisions/ bottlenecks appeared apart from the high workload / demand for support by AE and CAS.
• AE and CAS will crosscheck and provide feedback to PSPO regarding resources & priorities if required.

Dear all,

I updated the schedule for the tunnel access in the upcoming weeks based on the discussions in the PSO- and the Operation Board-meetings:

https://docs.xfel.eu/share/page/site/PSC/wiki-page?title=Tunnel_access_schedules

Cheers, Gerd

Dear all,

I updated the TAS to include the upcoming user runs up to and including the winter shutdown. As you can see, there will only be access to the XTDs in cases of urgency. In these cases, please contact Martin Dommach, Harald Sinn or Thomas Tschentscher.

https://docs.xfel.eu/share/page/site/PSC/wiki-page?title=Tunnel_access_schedules&listViewLinkBack=true

Cheers, Gerd

Dear all,

I received updates from DESY (M. Hüning) about how the access to the southern tunnels is being restricted in the next months, due to interlock tests etc., and included it in the TAS. Please check, if you have work to be done in these tunnels:

https://docs.xfel.eu/share/page/site/PSC/wiki-page?title=Tunnel_access_schedules

Cheers, Gerd

PSPO:

• Further commissioning of the PP-laser was started.
• Upgraded Karabo and PLC firmwares. Works are on schedule.
• Measurements on the dependence of humidity are ongoing.
• DESY is working on the timing system, laser synchronization will be down until the 21.1.18.
• PP-laser pattern selection with machine timing:DESY is now pushing for the originally planned implementation. DESY will have to do some software development in this context.

Detectors (J. )

• Tested the AGIPD @ SPB, but 1 board was not working. Detector consortium could not provide a replacement board, so only half of the detector was tested before SPB/SFX had to close the detector vessel again.
• LPD was tested with train builder, but only tests using 2 memory cells could be conducted (2 images per train), so train builder was not tested with all memory cells.
• More tests with full load (i.e up to 510 images per train) still have to be performed.
• Test with DSSC will take place in HERA South in CW 51.

ITDM (K. Wrona)

• Monday til Wednesday there will be no DAQ due to extension of the Infini-band bandwidth, upgrades, firmware updates, recabling etc.
• DAQ up again on Thursday

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

A. Mancuso: Will try to work around this, but in general a message one week beforehand would be required / appreciated.

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

Regard, Gerd

SPB/SFX:

• Mirror installation next week

FXE:

• Replaced broken diamond-window

SCS:

• Installation of alignment laser
• Mirror tank installation next week

SQS:

• Not present / no issues.

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.

Dear all,

below please find the hottest and most up-to-date times for the closing of the tunnels after the shutdown:

Cheers, Gerd
