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.

- EPS issues: any component driven to the beam was not protected by many bunches operation. The EPS was thinking the PNACT was closing but in reality, it was opened.
PRC/EEE/VAC/XPD OCDs solved by manually telling the system it is closed.
- Wrong bunch number sent to XGM: SA3 toroid was moved to a different position and the old name was not valid anymore. 
Info from this toroid was not received and the consequence XGM was receiving wrong bunch numbers. This makes impossible for the XGM to calculate correctly the number of 
bunches. 
Doocs servers were not updated (these programs would need to be informed of new naming).

MID:
- Joerg H. raises the question on the FFP2 usage recommendation. Sandra Plett says the document containing guidelines will be prepared (hopefully today); 
It is mandatory to use FFP2 masks if you are not alone; it also depends on the room size and at the moment it is 3-5 people in the hutches with mandatory use. 
A. Galler says these are the current regulations and maybe this will change in future.

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.

- 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.

DET:

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.
