- Nothing to report.

ITDM: 
- InfluxDB: large issues yesterday (cluster crashed on MON evening); it took all day yesterday to brought up and data is now visible also at Karabo. 
- ITDM has a root cause now and DAQ matrix devices were switched OFF yesterday which provides a fix. Last crash there was a lot of data that had to be synchronized and lacked resources. 
- ITDM found a way to start without data from Monday evening to Tuesday 21:00. This data will be injected to InfluxDB / cluster in the coming days. In the meanwhile, one needs to use Graphana to look at 
this data, not Karabo. 
- Discussing future measures to trigger alarm to avoid the crash. 
- Please don't start DAQ without the GO from ITDM via e-mail.

XRO:
- FXE jitter last week: not yet clear if it was the clean tent or the cooling water for M1/M2 the real cause; hard to find as cooling water was refilled and the clean tent was switched ON accidently, both 
in parallel. 

LAS:
- Issues with Sync system in SA1 persists: spurious 10Hz signal. PP-laser still do not have optical signal. LAS has a rough idea of the cause and is in contact with instruments.

UNSYS:
- Phase shifter in cell11/SA3 the motor was replaced and more 10 motors were ordered as spare parts.
- Quad mover in SA1#cell 18 was fixed.
- Quad mover in cell25/SA3 (wrong movement direction) is still to be addressed. MXL will work together with UNSYS.
- Tables for Phase shifters of Apple-X still to be uploaded.
- One new PS on the Apple-X is not working; Frank Brinker is informed and a ZZ is needed before the next blue week.

SPB:
- Influx issue but could use Graphana.
- Pulse energy is low this week: 2mJ while last week was 3.5mJ;
- Crosstalk with SA2: SA1 energy gets worse when changes happen in SA2 but recovers shortly after.
- SPB did not see any vibration on Tuesday 15.03. Also last week beam was stable.

FXE:
- Nothing to add.

MID:
- All fine at MID.

HED:
- Not present.

- Nothing to report.

General Announcement:
- On the Summer-22 maintenance period: In about 2 weeks (by end of March) the call for the summer/22 maintenance period will be send to the groups.

CTRL:
- Deployment of new framework in order to fix an issue (this week): instruments shall agree with CTRL contacts on a suitable time. It affects cameras and/or similar devices that are installed.

DA:
- Report on last week issue with processing on Maxwell including offline calibration: people were not able to open files that were there; small selected notes were not present and were corrected on Friday.
 Since then it seems no issues recurred.

- Starting equipment installation of SXP racks in rack rooms.
- PLC side calls from SQS on weekend: issues with motors to be followed up; train-IDs not getting proper.

VAC:
- Not present.

XPD:
- XGMD in FXE hutch under investigation: new issue happened at the end of the week and may be again related to last Monday's one. People are working on it (XPD, FXE and Desy).

DET:
- One comment to DA: Jolanta S-D was on DOC and issue with offline for ePIX detector still occurring after Friday. Phillip S. says it was a different problem and it is fixed.

ITDM: 
- Issue (2x) with Influx): still not understood; Data was not lost on last occurrence. Hick-ups and recovered. So far under investigation.

XRO:
- Jitter at SA1 in FXE last week: mostly likely the cooling in M1 and M2 or clean tent.
- No big issues after that.

LAS:
- Degradation in SA1 PP-laser with trigger software; maybe there is damage to optics. Being investigated today and can't guarantee when it will be working again.
- SA3 change of setpoint for SQS taking one-two days. Not sure if ready today.
- SA2 is running well.

UNSYS:
- Phase shifter cell11/S3: a ZZ is ongoing also fix with remotely procedure.
- Issue with quad mover cell18/SA1 is fixed remotely.
- Issue with Quad cell25/SA3: the ZZ is needed.

SPB:
- Issue with Agipd detector: fixed (one module not sending data). 
- Agipd online preview devices: fixed;
- Laser timing issue: data was not collected.

FXE:
- Jitter problem already mentioned.
- XGMD issue under investigation.
- Laser problem: stop measuring on Saturday. Not sure if data was taken during the weekend.

MID:
- Difficult week.
- Broker pileup problem on Monday and Friday: Gabriele says it may be related to a memory leak - under investigation. 
On Friday there were there sources identified to help getting rid of problems (Jolanta S.D); also GUI was a second source. Not fully understood the main source of Friday. It came back stable.
- Seeding beam had to be tuned on weekend as energy decreased by factor 5 when comparing to the best lasing at the week start. No scientific output could be achieved but feasibility with setup was 
demonstrated.

HED:
- Wednesday optics hutch ADC was not working. Now it works fine.
- Full power with RELAX was tested and is being analyzed. Bassler cameras acquiring wrong train IDs. It shall be fixed.

SCS:
- Not present.

- Successful week;
- Problem with motor being fixed by SQS, ME, EEE.
- Tool for online analysis was slow
- Heat load in the soft monochromator was seen and it has to be fixed in long term.
