Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 11.11.2020 |
General Announcement:
- XO is in contact with some groups regarding the winter shutdown, in order to get additional information or solve potential conflicts.
If there are any question, please contact us in this meeting or via e-mail.
- Steffen adds on the idea of using FXE for initial deployment of updated Karabo version. It will take place after 23/Nov.
- Jan asks how XO needs to be informed for tasks that groups deal with each other. A. Galler says XPD is on the list for setting a date to discuss this.
Groups are encouraged to communicate with other support groups beforehand.
CTRL:
- Misbehaving timing server at MID yesterday was initially solved by EEE. EEE replaced the hardware of the timing system itself but problem continued.
System seems now to be healthy but from time to time there are small timing interruptions. Investigation is ongoing and will be discussed in the digitizer meeting of Data
department.
- One CTRL ticket on Doocs device at SCS: it was a problem with custom installation. CTRL asks to be informed in case groups have custom installations. This may pose a
risk when deploying new updates.
DA:
- AGIPD train-ID issue: a small workaround until shutdown is in place. One has to set the individual channel and seems to be now working. Next intervention to take place
during Winter maintenance time.
EEE:
- Nothing else to report aside of the MID timing system.
VAC:
- Nothing to report.
XPD:
- SA3 XGM was switched to Ne as requested by instruments.

Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 04.11.2020 |
General Announcement:
- XO reminds on the 4.5MHz operation: MXL tested a 12hs switching mode and this will be used along the week.
The night shift operates at 4.5 MHz and day shift at 2.25MHz to avoid sending unnecessary bunches to the dumps.
CTRL:
- Issues with MC2 motors (bug in moving, mainly in SA3). CTRL has a fix but it is hard to find a proper time slot this week to apply it. The idea is to deploy next Monday
only in SA3 first.
If issues are found beforehand, please contact CTRL.
- SQS mentions a bug in the mirror observed yesterday which relates to the above described issue. SQS has to observe it to verify it moves all the way and then one can
wait until Monday for the fix.
DA:
- Nothing to report.
EEE:
- Crate issue in SA2: it was not needed to exchange the crate. A reboot on Monday afternoon helped to bring system back.
Crate works as normal. During winter shutdown EEE will replace crate and power modules.
- MID and LAS reported issues with train-ID / timing servers. Triggers have not been delivered in 10Hz. This is in discussion with DESY.
One solution is an update of the DOOCS timing serves that do not show errors which does not interrupt timing servers. In MID this may be related to data recording.
For the PP Laser further discuss with Desy colleagues will be made. This affects only MID because the use of old version of Doocs server.
- MCP problems reported by XPD: mismatch on the firmware version and EEE plans to upgrade this week.
- Preparation for the winter maintenance is ongoing and installations can start on 23/11.
VAC:
- VAC would like to thank EEE and CTRL for the SA3 loop vacuum fix.

- XPD found another issue with MCP: wrong assigned triggers. A ticket will be created.
DET:
- Update of MID AGIPD is still an issue but this is not critical at the moment.
- CTRL has accessed the LPD detector issue.
ITDM:
- K. Wrona informs ITDM has the reservation of Maxwell for data analysis during next two weeks.
The user groups have to be informed that one has to use Maxwell reservation to quick analyze data.
XRO:
- Nothing to report.
LAS:
- SA1 SPB PP-laser had to increase energy and is on work.
- SA2 PP-laser missing trigger from around 7PM yesterday. Laser went OFF due to this and luckily LAS was watching it and was able to switch ON quickly. LAS is in touch
with EEE and Desy.
A fallback solution could be to generate triggers by hardware but there is no progress from Desy side. LAS will prepare specifications for this module.
UNSYS:
- Small hiccup in one SA2 undulator that was remotely corrected.
SPB:
- Trying to align beam: SPB sees elliptical rings. Andreas G. suggests if this continues please communicate to the PRC.
FXE:
- No further information on issues with the LPD.
MID:
- Tomorrow it takes place the AGIPD train-ID meeting.
HED:
- Vacuum valves in differential pumping system were strangely closed on Friday 2AM. HED discovered this only yesterday. Pressure slowly went up. HED will further
investigate.
SCS:
- Not present.
SQS:
- 4.5MHz operation had gun trips due to the overheating of the dump.
F. Wolff-Fabris comments that was due to the radiation alarms on the dumps that removed beam permission by about one hour around 4AM. |

Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 02.11.2020 |
General Announcement:
- A. Galler reminds the attendance that this meeting is also an opportunity for making comments/questions on the new Covid-19 rules that start to take place.
CTRL:
- Main issue last days was related to the SA3 VAC PLC. The applied fix was left running during the weekend. So far it works faster and reacts faster for diagnostics.
CTRL is getting some statistics in order to get the final solution. If something goes wrong, please call OCD.
- No OCD calls during the weekend.
DA:
- No issues or news.
EEE:
- uTCA crate of SA2 balcony room is not reachable. A quick fix on Friday was not successful and EEE needs to power cycle or replace the whole crate.
This will interrupt timing for PP-laser and the signals sent to MPS. Meeting between EEE, lasers, instruments and XO will take place.
- (Note after meeting: the power cycle of the actual crate will be done today after lunch. If this does not helps then immediately exchange of crate will be done
afterwards.
PP-laser will be brought to a safe state and takes about 4-5 hours to restart it).
VAC:
- Nothing to report.
XPD:
- Worked at BKR with MCP detectors. XPD reported to CTRL an issue with ADC - some channels see no signal or not standard ones.

Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 26.10.2020 |
General Announcement:
-
CTRL:
- SA3 vacuum loops problems: seems to compromise some experiments. Beckhoff loops are changing states very quickly and compromises the whole system.
CTRL ask for the instruments to give info on the type of command given that makes motors change states. CTRL investigates together with EEE as more data has been produced
as compared to the past.
This problem does not happen in SA1/SA2 and may be related to the PES which will be checked this afternoon.

- The Winter maintenance period was adjusted yesterday. The ending period is now on January 13th, 2021, instead of January 4th.
CTRL:
- CTRL is reaching conclusions on recent Beckhoff problems:
1. CTRL would like to upgrade most of installations in instruments next week (upgrade of motors software). This upgrade is in general a step forward for the PLC
connections when it is dropped (re-starting).
2. For SASE installations, CTRL will make next week during machine days.
3. The GATT will not be upgraded now – this will start during Winter maintenance period. Upgrade of GATT is a priority for CTRL (has been added to the maintenance list
submitted to XO).
DA:
- Nothing to report.
EEE:
- Intervention in SA3 PP-laser was done.
VAC:
- No new issues to report.
- Maintenance on SA3 vacuum loop: in case of problems, one has to restart in PLC level with EEE staff and may result a bit longer recovery.

ITDM:
- OCD call data aggregator at MID
- need to understand better how to avoid the situation
- users complained to maxwell service (DESY directly) about limited resources becuase of high load by other users
- there are reserved nodes --> use them!
- issues with scratch
- more than 300 TB had been accumulated within a relatively short time
- it seems that data was calibrated to scratch not to proc
- MID comments --> a special calib mode was used that could not save to proc which is why it was saved to scratch
- problem with one of the proxy servers --> degraded performance of data migration
XRO:
LAS:
- issue at SA1 with Galvo
- after shift change to FXE, laser was not working --> Galvo was out of phase

- O. Henssler from DESY proveds the logs
SPB/SFX:
- coupling with SA1 and SA2 (SA2 using train on demand) is an issue
- beam walks off the XTD9 XGM aperture
- offset mirrors M2
- smaract cotnrollers
- most fixed by increasing timeout windows
FXE:
- shutter can be opened despite closed vavales
MID:
HED:
- damage on M3 mirror
- due to focusing scheme --> 9keV and intermediate focus --> during alignment unfortunately the focusing point came too close to M3
- meeting with XPD and XRO at 11:30
- hexapod issue reported to EEE is not quite fixed
- ´status is not reporting the correct status of the hexapod
- hexapod started working at some point and fell back to weird operation later again
- CRL arm7 seems to be at the limit of the x-axis
- if FEL stays where it is, XTD1 chamber might need to be moved
- JUNGFRAU issue
- up to a point the data is fine in the preview
- after some runs data seen in the preview is not written to file

Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 30.09.2020 |
General Announcement:
- XO informs the Call for the Winter Maintenance tasks will be sent to the support groups and Instruments today.
Please note it is not named "shutdown" anymore are critical services such as basic infrastructure must be maintained. At least in this round it will be called as "Winter
Maintenance" to avoid confusion among the staff.
The tasks list shall be sent to xo-planning@xfel.eu.
- In case of need to go to tunnel via ZZ, please contact the PRC at 9-4800.
- Gerd W. informs on the SXP construction work that starts on Nov. 23rd. The plan aims for a minimal impact in SA3 area at XHEXP1.
There will be new connections to the cooling water system in SA3and civil constructions.
Cooling water will be cut from Nov. 23rd until Christmas. This means rack rooms and laser will be affected.
- Gerd W. answers Raul V.: the cut cooling water supply does not involve tunnels.
- Tommaso M. says instruments need to have permanent cooling water supply.
Gerd W. states the electronics must be shut down and will not be able to re-start before Christmas as it takes time to empty the system, weld, do pressure tests and fill
it up again.
- XO suggests that SA3 instruments must coordinate closely with Gerd and also involve MB (Serguei M.).
- Nerea J. asks if this applies to SA3 balcony room also. Gerd W. says that the rack rooms will be affected.
- Gerd informs there is a series of meetings taking place on Thursdays at 14:00 and this construction work can be addressed. The SCS and SQS group leaders have been
invited to this series.
If someone else wants to participate, please contact Gerd W. for getting the Zoom link,
- Monica T. says that this lack of cooling water may impact the DSSC move to SQS by delaying its test.
CTRL:
- CTRL experiences some login hiccups related to information sent to InfluxDB. This will be fixed Sunday night (Monday at 02:00AM). There is no reason this issue will
affect devices until the fix is done.
DA:
- Train-ID investigation for AGIPD offset is ongoing. DA understands from now on DET is responsible for the leading efforts.
- Monica T. comments it has been identified the issue related to the AGIPD firmware (2019 version, accordingly to Jolanta). This will require a significant change and to
do it now is not an option.
The good news is that this is a systematic issue and DET know how to take care of it.
- A. Galler asks the small task force on the train-ID to make a small presentation during next XO Integration Meeting.
EEE:
- ADC in PP-laser (SA1) is confirmed to be solved.
VAC:
- Nothing to report.
XPD:
- Nothing to report.
DET:
- Issue with DSSC yesterday: one Interlock signal was permanently enabled. EEE solved after restarting the device. It will be further investigated.
ITDM:
- Desy/IT requested ITDM a time slot to fix redundant parts of the routers between "ours" and "accelerators". To do so Desy/IT and MXL suggests to apply the fix (do not
expect side effects) today before lunch time.
No relation to the timing system of lasers is expected (low risk). None in this meeting's audience raises an issue against the proposed time.
XRO:
- Nothing to report.
LAS:
- All 3 PP-lasers are up. Currently LAS still make some studies and instruments must send a message in case the need of use. Lasers are ready to be provided to
instruments.
UNSYS:
- A ZZ is currently ongoing to fix issues with failed couplers in SA3 control cabinets.
- Beckhoff replies the cause of failure is either an overload of current or relations to temperature. Temperature seems not to be the issue (accordingly to UNSYS).
SPB:
- Nothing to report.
FXE:
- Plan to test digitizer (HQ412): issue is that sampling rate is not reproducible as in the lab. Probably it will happen tomorrow together with PP-laser use.
MID:
- The vacuum issue with the monochromator is under control.
HED:
- Preparing the user next week (that uses the pp-laser).
SCS:
- Nothing to report.
SQS:
- Nothing to report. |

Frederik Wolff-Fabris | General | Information | Notes XO Integration Meeting 28.09.2020 |
General Announcement:
- Andreas G. informs the winter maintenance period will happen in two months approximately. The call for tasks will go out this week to the support groups and
instruments.
- XO informs Desy and TS are investigating the Thursday's event of power cut but do not yet have a clear reason for it.
- Jan G. informs that SCS hutch will be closed and searched this afternoon for the FD on Gain Studies.
CTRL:
- Notification service informed on a broken event. After a Karabo shutdown the FXE topic is fine again.
- Power cut: CTRL sees no issues as leftovers.
- Investigation of missing data in DOOCS (10 seconds outdated): CTRL has two colleagues looking into it.
- Supporting EEE and LAS on the ongoing working with PP-lasers.
- Update of dataloggers has to be made again. It means a 2 minutes downtime during the course of today/afternoon if nobody has something against.
DA:
- Question to CTRL: a notification service was forward to us. DA needs further description on that. Steffen H. says it was related to the python server and this is not
deployed by CTRL.
This is the reason why was forward to DA.
EEE:
- Follow up from Friday recover on the power glitch of Thursday: some cards in SA1 balcony rooms were not reachable anymore on Friday. These lead to a complete restart of
the whole crate (means interruption of timing). After additional local intervention communication to the MPS was restored.
- Changed the fast ADC of PP laser in SA1.
VAC:
- Nothing to report.
XPD:
- No issues to report.
DET:
- Agipd was power up after the power cut and had no issues.
ITDM:
- Nothing to report.
XRO:
- Nothing to report.
LAS:
- SA3 PP-laser: problems with SQS site. It misses the power energy (dropped down) and is under investigation. Maybe it is related to some optics assembling.
- SA2 PP-laser: power supply for AMPHOS was lost on Friday. The spare part arrives today at 11:00 and will be changed this afternoon.
- SA1 PP-laser: problem with uTCA (no ADC running and not possibility to login). Crate hangs after every few hours. Working together with EEE (100% in EEE side).
UNSYS:
- The problems with cell1/SA2 not moving were fixed by Suren K.
- Cell2/SA3 hardware problems (couplers) found this morning relates to an Ethernet card which needs to be replaced by ZZ. This cell is not operational.
- Phase shifters in SA3, cell4 and cell5 are not moving. The hardware works and it may be some higher level controls.
- Couplers were sent to Beckhoff for further investigation in order to find solution for decreasing the number of failures in future.
SPB:
- Nothing to report.
FXE:
- Due to issues with PP-laser the FXE did not test the timing tool during the weekend.
MID:
- All fine: still minor vacuum issue in the optical room but MID hopes to be solved soon.
