General Announcement:

- Today is the last xo-integration meeting for this year. Xo wants to thank everyone for the participating in this meeting series while sharing information and giving updates.

- The next XO Int. Meeting will happen on 04 January.

CTRL:

- Beckhoff MC2 motor upgrades at SA3 is ongoing.

DA:

- no updates

EEE:

- all SA2 fast ADC tasks have been concluded.

- Cabling in HED is ongoing; On MID will happen next year.

- AIBS control at SA1 balcony room installation starts today.

- Testing Mc2 motor configurations in tunnel devices.

VAC:

- Trying to finish main shutdown tasks: GATT, new mirror chamber in SA3/SXP, SA2 M3 mirror chamber.

- M3 chamber InGa is clean and ready to be pumped down.

- XGM/SA1: broken gate will be replaced this week or next.

- Some members of VAC group are working on site next week.

XPD:

- XGM SA2/XTD6 was moved 4mm and is still in alignment (no damage found) -> Jan G and Harald S. will have a look today onsite. M. Dommach says the differential pump could not move that far away due to bellows. 

- Installing of switches for HRIX will be most likely finished this month and some maybe in January.

DET:

- nothing to report.

ITDM:

- nothing today.

XRO:

- Not present.

LAS:

- Laser Hutches are locked (no access allowed) by Safety and LAS members can not continue the work in laser rooms. LAS maintenance tasks can not be finished and may be delayed over the end of shutdown.

- Emission of SASE2 Seeder laser was put in OFF yesterday due to inspection by SLSO. This means laser was OFF and there is no guarantee the PP-laser will be available in February, as they will not start mode-locking again after an Emission OFF. 

- Typically the Seeder lifetime is 3-4 years. Each time it is switched OFF it shortens the lifetime by half. If Seeder is included in the Interlock system, and taking into account the interlock trips 1 time per week or month (case of SASE3), the availability of PP-lasers is in risk and consequently the whole operation for instruments.

- Alignment lasers will be no longer provided. This also relates to the safety decision - such lasers are not allowed to be operated.

UNSYS:

- not present.

SPB:

- nothing to report: quiet days.

FXE:

- Craning activities over the hutches due to SXP construction still ongoing: not always a notice from construction workers.

- nothing to report

General Announcement:

• Due to work restrictions, some of shutdown activities will not end as planned in time. This leads to a prolongation of the start-up phase starting next week. It means re-start of Accelerator and South branch will be delayed by 2-4 days while the North branch by about 1 week.
• The first 2 weeks of X-Ray delivery (2.2-15.2) will most likely be affected and photon delivery cannot be guaranteed into all beam-lines at all days. Some flexibility in planning for the commissioning tasks is expected. A detailed schedule for an upcoming week will be available on the week before, latest on Friday.
• Sara C. asks if tunnel access is allowed during this week. F. Wolff-Fabris understands tunnels still can be accessed this week apart of Covid regulations (in the context of tunnel maintenance tasks that have to be performed while tunnels are open). T. Tschentscher says the understanding is from Robert F. guidelines e-mail are still valid for this week and really important tasks may be conducted – an e-mail to Robert and Nicole pointing the task with the need of access could be sent. Steve A. reported from today’s Covid taskforce meeting that the regulations of last corona email are still valid - if there are any question send an email to health@xfel.eu.

- If there are short circuits or mal functions in the Beckhoff crates and current is not high enough to trigger the fuse it may be a fire risk. Solution is developed without impact in firmware, just a replacement of fuses. EEE starts today at SPB the changes; Based on this experience a plan will be made for the other systems and EEE will get in touch with groups.

VAC:

- try to get the works finished in the tunnels

- waiting for the Beckhoff crate works

XPD:

- Most of the tunnels works have been done; others are ongoing; No surprises are expected.

- MKK logbook from Desy reporting about electrical issue. XO will check. (XO update at 13:30: automatic mailing system is being commissioned and under testig; no power failure happened at the time).

DET:

- Work with DSSC in SQS going as planned.

ITDM:

- Work currently being done at FXE.

- Reminder of Friday afternoon gateway update.

XRO:

- Not present.

LAS:

- Nothing special to report.

UNSYS:

- Greasing the linear stages for undulators but not in SA2 (missing grease).

- SA1/SA2 after middle plane alignment UNSYS redefined the minimum gap and will be communicated through XO.

- Cell#36/SA2 there is a cable disconnected that need to be fixed.

- SA1/SA2 working with PS tables for extending operating tables for higher photon energies.

SPB:

- Work with EEE changing all the crates (Beckhoff)

FXE:

- Nothing to add

MID:

- Several ongoing infrastructure works are going fine.

- Worried with Beckhoff fuses (reported two years ago by Konstantin). It will be good to hear experience with SPB.

HED:

- Nothing to add

SCS:

- Nothing to add

SQS:

- Nothing to add

General Announcement:

- Power glitch 3 times at night, what brought down the beam for 1,5 hour each time. Please report to XO if you find devices affected.

CTRL:

- Datalogger update to take place today between 16:00-17:00. Please inform CTRL in case of problems with this schedule.

- Aravis camera and bunch pattern decoder to be updated at around 14:30. Please inform CTRL in case of problems with this schedule.

DA:

- OCD side: no new problems.

- Follow up last Wednesday: better is to use the new Karabo with the fix and not to downgrade the Karabo version.

EEE:

- Ticket from SCS was solved.

VAC:

- Some trouble with the pumps in the gas attenuator SA3. It needs to be fixed today in the tunnel with a ZZ (30 mins).

ME.

- Not present.

XPD:

- Are investigating, if something is affected by the power glitch. So far nothing was found.

DET:

- Nothing to report.

ITDM:

- Two issues to follow with MID: 1. Bassler camera seems to be the data wrongly recorded at DQA. Tests need to be done; it’s a camera used for feedback. Ulrike B. will talk offline with K. Wrona.

- Second issue: on Friday there was one ADC from tunnels to be used from MID was requested a bit late. Data comes from the uTCA from Desy network. If this device is going to be used in full, it has to be set inside Desy network.

XRO:

- Not present.

LAS:

- Two incidents: the power glitch at 19:23 yesterday took Amphos in SA1 down. It is back and operational; In SA3 LAS is further investigating the Amphos.

UNSYS:

- No problem with the power glitch.

- The temperature in SA3 Undulators is stable.

SPB:

- SPB imager at XTD9: is not working and has to be changed the outcome needs to be fixed of XPD. Naresh K. will contact SPB.

FXE:

- Not present.

MID:

- All good at MID – not heard on affected systems due to the power glitch.

- Friday afternoon confusion with the fix of Extra Foam bridge. Probably DA is aware.

HED:

- Vacuum system ok after power glitches.

- Nothing to report.

SCS:

- Not present.

SQS:

- Not affected by the power glitch.

General Announcement:

- No general announcement.

CTRL:

- Problem with cameras / DAQ: fixed yesterday and tested at SA2/MID.

- Issues with SA3 vacuum loop: work ongoing and further investigations are needed.

DA:

- Nothing to report.

EEE:

- Cables available for HED to be installed next week – date to be discussed offline.

- Fast electronics side: working on FXE and HED issues;

- Nerea J. reports on the VAC/SA3 issues: instability with devices going into an unknown state. Alessandro S. works at the night shift in the DOC and will try to fix a permanent fix during the night.

VAC:

- SA3 issues are affecting also the gas attenuator (not only general SA3 vacuum loop but also GATT is affected, which has its own loop). There are no physical events - seems to be electronic. Stability issues to connect devices; Seems to be more related to infrastructure (PLCs). Further investigations are needed.

ME:

- Not present.

XPD:

- SPB imager: change setting of motors (it shall work now) and next week when A. Koch is back further investigations will be done.

DET:

- During the night after 02:00AM: SPB AGIPD K-bridge went OFF. Under investigation. Detector recovered this morning.

ITDM:

- Nothing to report.

XRO:

- Not present.

LAS:

- Nothing special to report.

UNSYS:

- Nothing to report.

SPB:

- Issues with wings of Agipd, causing also interlock trigger. Under investigation.

- XTD9 IMG: currently working but a permanent fix is welcome in the future.

FXE:

- Not present.

MID:

- All fine.

HED:

- Major issues with Agipd detector yesterday (thanks to DOC for help): 1. Could not kill the service and CTRL investigated; 2. Clock and control did not work (it has worked at CFEL last week). The issue was solved by changing the clock controller back to old configuration (EEE helped). Bruno F. comments that the clock control had to be downgraded in this detector (it worked in other detectors, only this one did not work). Further investigations will follow.

SCS:

- Change of speed from the monochromator was not possible. EEE and CTRL are working on it.

- Next week will run with a special train picker / bunch sequence pattern as the one used last week.
