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.

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.

- 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.

- 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. 
EEE knows and runs some scripts - this happens from time to time and may affect recording data.
- In general, from XGM side, Theo M. has prepared a way to switch settings to extreme changes of photon energies.

DET:
- Nothing to report.

ITDM: 
- Nothing to report.

General Announcement:
-	 

CTRL:
- SA3 VAC loop - 2 approaches to find out the root cause (discussed also with EEE):
1. Thursday 8-11:00AM to test the whole loop by partitioning batches of devices. This may pinpoint the single device that cause the problem.
2. Reproduce the problem at lab level. Based on the reproducibility this approach will be continued in parallel. 

DA:
- Nothing to report.

EEE:
- PLC colleagues are troubleshooting SA3 VAC loop.
- DET reported that measurements are carrying on wrong train-IDs. Tests are being made in the lab (not reproducible) but EEE is working on it.

SCS:
- Issue with door interlock: Eric B. has investigated this morning. Problem seems to be with the maglocks and has been solved for now but a long term has to be worked on.

SQS:
- Nothing to report.

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.
- Please call the new OCD numbers: 6541 and 6542. Specially on weekends it is the fast way to contact. This number is valid since last spring.

DA:
- Nothing to report.

EEE:
- Nothing to report.

VAC:
- Nothing to report except of SA3 vacuum loops.

XPD:
- Not present.

DET:
- XO asks on the train-ID progress of Agipd. Monica T. says that the plan is to correct in the DAQ level during the next shutdown. 
K. Wrona adds that the fixing takes long and the current investigation focus on doing in the DAQ level during January.

ITDM: 
- Maxwell nodes used to login in the Maxwell will be rebooted today, causing access limitations.

XRO:
- Nothing to report.

LAS:
- Bunch pattern in demand: LAS assume XO will take care of this topic. Andreas G. says XO will take care but need to be informed on what is needed. 
Tomasz J. mentions it needs some coordination between instruments and machine.

UNSYS:
- Couple of issues in SA3 undulator cell: it got stuck, mostly during machine development times by running out of range. This was corrected during the weekend.

SPB:
- Moving on with WP8. Continuing today.

FXE:
- Nothing to add.

MID:
- MID makes a general reminder on the train-ID development with AGIPD: MID expects to have a meeting to discuss a long term solution plus the test procedure for 
implementation after the quick fix. 
This has to be planned in advance.

HED:
- Nothing to report.

SCS:
- Nothing to report.

SQS:
- SQS has suffered during the weekend with the VAC issue.
- CTRL side can look at the PES this afternoon.

General Announcement:
- XO thank the effort made by preparing the activity lists for the maintenance period. In few cases XO is contacting groups back with questions and/or comments.
- 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. 
Steffen H. comments it has been worked on and may be solved in the next day or so. The restart procedure is easy but lengthy. CTRL/OCD knows what to do.
