• 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.

XRO:

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.

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.

DET:
- Preparation for activities on AGIPD at SPB/SFX during the winter time is ongoing.

ITDM: 
- Pre-announcement: at the start of the maintenance, ITDM has activity on the computer cluster. A separate announcement will be sent.

XRO:
- Nothing to report.

LAS:
- Nothing to report.

UNSYS:
- Nothing to report.

SPB:
- No issues to report.
- Intervention date of AGIPD: SPB requires due to highest priority work that between 16/11-18/12 no interruptions of electrical power or the need of EQP may happen. 

FXE:
- Crosstalk SA1/SA3 was not seen yesterday as SQS used only 1 bunch.

MID:
- Nothing to add besides what CTRL and EEE have mentioned.

HED:
- Next week HED does not use X-ray beam: commissioning of the high power laser and test of pulse on demand are planned. A. Galler says it pulse on demand was fixed by 
CTRLs and can be used. 
- Question on use of ADCs: Bruno says some trains will not be recorder or be repeated. This may be related to the timing issue like in MID. 
But data can be acquired. It is under investigation accordingly to Bruno, with CTRL, DA, ITDM.

SCS:
- Not present.

SQS:
- Nothing to report.

General Announcement:
- Maintenance summary task list has been made available at the S:\ folder as well as in the XO Alfresco page.

CTRL:
- On Thursday laser1 went down: error on deployment related to fix zero train ID.
- Lasers safety deployment is fixed.
- SA3 vac loop: progress was made and new version of Karabo needs re-start this morning.
- SA3 fixed MC2 motor issues. Coordinated with instruments to do tests today.

- 1 OCD was received and solved during the weekend.

EEE:
- Announces that on tomorrow's PBS there will be a EEE presentation on the Digitizer instruments.

VAC:
- Nothing to report.

- No issues. The switch of XGM settings at different energies went well.

DET:
- Nothing to report.

ITDM: 
- Meeting with MID on train-ID is set. There is a mitigation error plan which will be implemented.

XRO:
- Nothing to report. Minor issues on CTRLs but are not stoppers.

LAS:
- PP-laser for SPB run was interrupted for 45 minutes.
- Issue with synchronization / motor becomes unstable, relating to motor slippage. Hardware will be replaced during the shutdown.

UNSYS:
- Nothing to report.

SPB:
- Finished user experiment: went OK but machine not very stable. Intensity and pointing very unstable. After beam losses timing came quite different. 
Data for pointing quantification to be analyzed.

FXE:
- Unstable beam the whole week. 
- Crosstalk between SA3 and SA1: sometimes BKR could fix/work on it, sometimes not. This happens when FXE runs at 150 bunches and SA3 varying 1-100. 
SA1 intensity goes down by factor 2.

MID:
- DET and ITDM contacted during the weekend.

HED:
- Not present.

SCS:
- Not present.

SQS:
- Crosstalk SA1/SA3: night shift crew said it is not a problem for next week if run without Interleaved.

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:
- 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.
