- Problem on Monday with quad mover cell18/SA1 took 6 hours on ZZ. It is now fixed.

- A problem with undulator segment on cell36/SA1 needs diagnostic and eventual ZZ access. RCs are contacted.

SPB:

- The samples to be used next week are challenging to prepare. 

FXE:

- Used beam yesterday. No problems to report.

MID:

- all fine.

HED:

- nothing to report.

SCS:

- nothing to report.

SQS:

- all good.

General Announcement:
- Following Desy e-mail to all EUXFEL staff, the emergency call system of the elevators will be offline on Thursday March 18th during the morning. Please avoid using the 
elevators in this day. 
- On March 23rd is scheduled the SEPS interlock tests in SA3. On March 25rd is planned for SA2, pending a confirmation with the machine on the impact in SA1 operation.

CTRL:
- Progressing with investigating the train-ID issues, currently it relates to DOOCS/Desy.
- DOC: reports one fix today at 13:00 (following a call). Please respect a sign "we are in", "we are out" at the DOC to help staff focusing on issues. 

DA:
- Nothing to report.

EEE:
- Nothing to report.

VAC:
- Nothing to report.

XPD:
- All working fine in XPD.
DET:
- Detector commissioning in SPB: AGIPD was completed as planned and Jungfrau seems to run properly (data to be analyzed.

ITDM: 
- ITDM will add more space to the storage system (data taking). Initial idea is to make it on March 30th to minimize impact. Acquiring data and data analysis are not 
impacted. 

XRO:
- Beam power increase ongoing.

LAS:
- An issue with SA1 interlock in PP-laser room: the inside doors were reported to be open on Thursday afternoon. 
As SPB was not using the PP-laser, the laser was put in safe mode and Interlock was broken to access and verify the situation. The internal doors were closed. 
Further discussions will follow. This door issue happened for the first time in SA1. 
- LAS is providing beam to SPB and HED as requested.

UNSYS:
- Couple of e-log entries on settings of air coils and phase shifter, all addressed during the weekend.

SPB:
- Detector program is completed. One measurement (which is not critical) is missing from Jungfrau.
- Interacting with DOC worked nicely.

FXE:
- Preparing for this week.

MID:
- Fully in preparation for first April beam. All fine.

HED:
- Nothing to report.

SCS:
- SCS asks for update of missing CPU from EEE. No news from EEE. Contact will be made.

SQS:
- Preparing to have beam in April.

General Announcement:

- nothing for now

CTRL:

- A few issues for DOC: Cameras IP addresses need to be reconfigured

- Continuing investigation of train-IDs on Doocs/XGM (they oscillate). CTRL will follow and close contact with Theo M. and Desy colleagues.

DA:

- nothing to report

EEE:

- nothing to report

VAC:

- nothing to report

XPD:

- Not present.

DET:

- nothing special – commissioning this week

ITDM:

- nothing to report

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.

UNSYS:

- nothing to report

SPB:

- going on with the plan; Detector commissioning from tomorrow.

FXE:

- the floor works are ongoing - looking good.

MID:

- not present

HED:

- nothing to report

SQS:

- Staff is getting the search training which was expiring.

- Noticed issues notice with DACHS system which show the access properties with delay. 

General Announcement:
- SPB/SFX will continue receiving beam this week for commissioning.
- Issues with access to the Operations/21 e-log: SPB run coordinator wrote to wrote to the admin but no answer so far. Entries by Adrian M. while using VPN also did not 
work. 
XO will follow with IT (see below).
- Gerd W. reports that works in SCS chicane are done and the radiation interlock keys are returned.

CTRL:
- Some observations triggered by DOC regarding XGM trains coming too late (20s). An update will be made later on the day or next days.

DA:

ITDM: 
- Janusz S. says on the e-log issues that administrator of the e-log has the power to include new people. 
While using VPN access one can read the e-log and post entries using the copy function from another e-log. Nothing in the procedure has changed from past time.

XRO:
- Nothing to report.

LAS:
- SA1 PP-laser recovered power for SPB and is delivering in the nominal power level.
- SA3 AMPHOS was switching off at random during the weekend; no reliable operation in SA3. LAS is in contact with external company.

UNSYS:
- Cell4 and cell6 in SA2 required intervention from expert (Suren K.) during the weekend. 

SPB:
- Drift of horizontal beam position was observed on the weekend and reported to the DOC which provided a tool to diagnostic the drift. SPB/SFX would like to thank the DOC 
for the availability.
Beam pointing was changing every hour and was difficult to keep into M1 and M2. Theo M. says the XGM drift happened in the horizontal by many mm. DOC can not solve and 
then contacted Optics group. 
The observed drift seemed to be too big to be compensated. Richard B. says the movement was seen from XTD9 XGM and was a fast drift. 
Andreas G. will address communication channels between DOC/DRC and PRC (PRC was not informed). 

FXE:
- Floor refurbishment starts today.
