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.

• 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.

- After interlock test last week there is an issue with the new DACHS terminal. The hutches can’t be accessed. Pouneh S. says DACHS is working but this particular new terminal might not be activated in the system. An special permission must be given. Tobias Haas will be informed to contact MEA3.

FXE:

- Martin K. will ask FXE colleagues on YAG screen information. Currently he is not aware when this happens (similar event back in 2019). 

MID:

- all fine.

HED:

- all fine.

SCS:

- in contact with Eric B. to get the beam shutter back on Friday for closing hutches during the weekend.

SQS:

- Early next week review with the digitizer engineers.

- Pouneh S. asks that laser interlock in laser hutch does not work. The new parts have been shipped and arrive soon. Together with TS electrician one has to exchange the relay. Daniel Rivas is informed.

General Announcement:

- Due to a failure alarm in the smoke extraction system in XTD6+8+9, Desy colleagues will need to reboot a crate and exchange one module. This will bring down the air conditioning for the tunnels during about two hours. The activity is scheduled for March 1^st starting at 11:30AM and it appears in the EuXFEL infrastructure calendar.

- It has been found a situation with one of the elevators to the XHEXP1 Hall. Due to corona regulations a maximum of 3 people is allowed simultaneously in the elevator. This number is indicated by signs/papers fixed nearby. However, someone unauthorized has modified the number “3” to an “8”. We are investigating the situation. The shields have been corrected back to “3” but we would like to remind signs and warnings must not be modified by unauthorized persons.

- Gerd W. informs that SXP chicane modification foreseen to take place today and tomorrow is shifted to Monday or Tuesday due to delays in delivery of components. Affected people have been contacted by PMO via but in case of issues with the new plan, please contact Gerd W.

CTRL:

- Few requests for tickets on Karabo devices were received. CTRL reminds to please add device ID in the ticket.

- SA3 motors: a few changes were done due to migration of MC2 motors. If someone or a group needs more input, please directly contact Steffen Hauf.

- Regarding Data Operation Center (DOC): CTRL would like to have a functional account to the instrument e-logs to be able to access it and track problems when OCD gets called. If instruments have any concerns with this, please contact Steffen Hauf.

DA:

- Nothing today.

EEE:

- No main issue.

- EEE also asks that when submitting tickets, please include the instrument and component name, preferentiably in the header.

- Nothing special.

HED:

- Thomas Preston asks if the Covid regulations in hutches can be sent by e-mail. Sandra Plett will send the link to the documents after the meeting.

- The mask occupancy for the hutch was changed (are the signs updated or not?). Thomas P. says it was 4-5 but someone wrote new numbers in the signs. Sandra P. says that if everybody is using FFP2 masks, then more people are allowed than the max. occupancy.

- Pouneh S. says if people use laser safety googles, one can use FFP2 with filters. Sandra P. says that rules also apply for this case.

- Issues with cameras: DAQ did not run (did not take data, probably due to lost configurations). HED will send ticket.

SCS:

- Nothing to report.

SQS:

- Yesterday a meeting to review digitizers took place.

General Announcement:

- Hick-ups in the beam operation are happening since last night. There is no obvious indications on the origin of the problem and MXL is investigating to restore a normal beam delivery condition.

- There is an issue with “Operation-2021” e-log where some SPB staff can’t login to create entries. This will be addressed by XO/PRC and ITDM (see ITDM entry).

CTRL:

- SA1 DAQ was dropping some trains (the late ones) in the XGM. CTRL and ITDM are following up and will test the XGM late this week or next week. CTRL will contact XPD for deployment first in SA2 and SA3.

DA:

- News from the DOC: deployment of major updates ongoing/to take place.

EEE:

- nothing to report

VAC:

- not present

XPD:

- Commissioning and setting up for SA3 HIREX

DET:

- preparing for commissioning Detectors

ITDM:

- Janusz S. says the configuration for the “Operation-2021” e-log uses the same configuration as previously set for 2020. F. Wolff-Fabris likens the issue with possible new users and asks SPB to provide the name of users who can’t login into the e-log.

Janusz S. says one can use the copy function from instruments e-log to place a copy into the Operations-2021 e-log. Jan G. says that login is necessary to avoid the entry being as “Anonymous”.

XO and ITDM will address it offline.

XRO:

- not present

LAS:

- In SA3 PP-laser one had exchange of power supply for AMPHOS due to communication errors.

- In SA1 PP-laser one observes a loss of 1/4 of power in AMPHOS. LAS is not sure if there is enough power for users.

- Two problems with triggers on Monday: 1. a faulty board in SA3; 2. MCS group update timing system caused trigger loss in all hutches (due to a bug in their server).

UNSYS:

- nothing to report

SPB:

- Couple of Helps asked to DOC and SPB/SFX are thankful for that.

- Login at Operation-2021 e-log does not work for 4 people.

FXE:

- Prepared for AIBS. Few PLC problems remain but not related to AIBS.

- Next week between Tuesday/Friday there are no access to the hutch due to floor work ongoing.

XRO:

- Maurizio V. reminds the SEPS interlock check in SA3 still has to happen as it is a condition prior beam operation. Zunaira A. says she sent an e-mail to xo-planning.

F. Wolff-Fabris asks if the SCS door is fixed or not, a pre-condition for the test. Zunaira A. replies the problem was with the power supply to the door and is fixed.

A date for the SEPS test can be planned by XO.

LAS:

- SASE2 interlock: LAS got unexpected calls when disconnecting AMPHOS cables (thus triggering SA2 Interlocks).

- SA3 AMPHOS no news since Monday. The ADC cards do not receive train-IDs.

- LAS suffer of lack of laser lab, missing PLC installation. LAS asks XO for a follow-up on prioritizations.

- Zunaira says that lasers are coupled to the interlocks (yesterday event happens as all lasers in room A23 and A07 are connected to the HED and MID interlocks). Thomas Preston says it triggers the warning lights for the laser lab. Zunaira A. says if shutters are closed it shall not be a problem if lasers reach this shutter signals. Tomasz J. says that ideally they must be decoupled.
