General Announcement:
- Adrian Mancuso tells on the workaround for the crosstalk between SA1/SA3 documented by Harald Sinn. The idea was to switch off the feedback prior the bunch changes. 
Harald S. says that it is not sure if this has worked. Adrian M. says that fir the future this has to be addressed as both SA1 and SA3 would like to change bunch number.

CTRL:
- Follow up from the DOC last week: some cameras in HED started in unexpected states. This has been understood and when the update is ready the deployment has to be 
coordinated with HED.

DA:
- From DOC OCDs side only minor issues, that were solved by restarting devices.

EEE:
- Due to the special FD week starting today, there is no DOC this week. 
The DRCs (Patrick G. until Thursday and Monica T. from Thursday) will receive the calls: for normal issues, please send a ticket; for urgent cases call the DRCs. 
One can also contact directly the individual groups.

VAC:

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:
- Suren K. informs Beckhoff Hardware for cell#31/SA2 was received and is under test. As soon UNSYS is ready for a ZZ it will inform PRCs for scheduling a date. 
Mostly likely ZZs will occur on Tuesday and not Monday due to continuation of 11.5 GeV studies. 
- Communication problem with one undulator on Monday was quickly fixed.

SPB:
- Working on nano KB mirrors.
- 5 keV last night: gives right trajectory. It looks like the beam performance was sufficient for SPB alignment. Fine tuning has to come.

FXE:
- Affected by the shutter problem during the tentative ZZ access yesterday.
- Solid Attenuator issue in discussion with EEE.
- Sampling rate of ADC has changed. Peter Z. contacted EEE and it has been accessed.

MID:

- Pulse picker is not behaving correctly. It may be a Hardware issue and has to be investigated. Then HED will communicate to EEE.

SCS:
- PP laser was down last night and the OCD was contacted. There is the suspicion the crystal is damaged and the OCD informed it will be fixed this morning. 
Daniel Kane will try to get some info inside LAS and report back t SCS.

SQS:
- It has users this week and shutter becomes a serious issue. In Karabo the shutter state changed but it is disconnected. It is not clear if the ZZ team is progressing 
right now.
- Problem is that when trying to close the shutter via JDDD interface it went to an intermediate state but shutter did not close. 
This cause interlock not opening the hutch and the beam could not be sent to the hutch. No beam since 5PM yesterday. Also locally operated in the panel it does not work. 
The JDDD interface worked nicely the whole last week. Eric Boyd asks if problem appeared at the first operation. Tommaso M. says they did a lot of times prior having this 
issue.
- Waiting for updates from CTRL mentioned.

how long it takes to fix it.
- TS requires location knowledge of all office chairs. In case you have taken yours to home, please let TS know.

CTRL:
- Reports from DOC with delayed train of DOOCS XGM for HED. It will be investigated.
- Reminder that it is a blue week and the DOC does not run. The DRC is available via phone.

DA:
- Issues with the offline calibration system: changes of data migration (how it works). Hot fixes are ready to be deployed (probably today); please check the migration and the auto-run; DA will update 
after the deployment.

EEE:
- Nothing to report.

VAC:
- No problems with power glitches.

XPD:
- XPD side: all fine.
- As PRC, Jan G. says that pump-probe laser at FXE was affected on Friday morning (Laser unavailable until the night). On Saturday and Sunday the lasers were not affected due to the power glitches.

DET:
- Nothing to report.

ITDM: 
- Gitlab update taking place this week.

XRO:
- Not present.

LAS:
- None of the PP-lasers went down this weekend in relation to the power glitches.

UNSYS:
- Nothing to report.

SPB:
- Adrian M. asks that, in case supply problems continue to happen, would that mean EuXFEL makes proactive action for operations? 
A. Galler comments that DOB will discuss the issue with lasers (exchange of pumps that are vulnerable to the power glitches is planned for the winter shutdown). From machine side, as it is largely 
unaffected, the operations calendar won't change.

FXE:
- Nothing to add, no news on clock and control upgrade.

MID:
- All fine at MID.

HED:
- Not present.

SCS:
- Nothing to report.

SQS:
- Dismount the DSSC and give back to SCS this week. 
- SQS expect beam for the safety tests on Wednesday and Thursday.

General Announcement:

- Interlock test next 2 weeks starting on monday - from next wednesday the photon tunnels will be closed; Tests are the XHEXP1 take place on 30.06, 01.07 and 02.07 with the last date as reserve; An email is going to be send by FWF to the xo-info@xfel.eu list.

CTRL:

- List of items to be sent to readiness: 1. problems with lima based cameras (Lima library does not work – needs to be updated: instruments contacts shall get in touch); 2. In SA1 there is legacy Undulator Karabo scenes – vector properties have to be adapted; 3. Counter Clocking motor devices upgraded next week.

- A. Koch asks if SA1 was working this morning. Steffen H. says there were updates but must be running now.

DA:

- Next wednesday will be the Offline calibration update deployment

EEE:

- Shutdown activities going well; "Wille" is short in people but scheduling adjustments with FXE and MID is organized.

- If there are short circuits or mal functions in the Beckhoff crates and current is not high enough to trigger the fuse it may be a fire risk. Solution is developed without impact in firmware, just a replacement of fuses. EEE starts today at SPB the changes; Based on this experience a plan will be made for the other systems and EEE will get in touch with groups.

VAC:

- try to get the works finished in the tunnels

- waiting for the Beckhoff crate works

XPD:

- Most of the tunnels works have been done; others are ongoing; No surprises are expected.

- MKK logbook from Desy reporting about electrical issue. XO will check. (XO update at 13:30: automatic mailing system is being commissioned and under testig; no power failure happened at the time).

DET:

- Work with DSSC in SQS going as planned.

ITDM:

- Work currently being done at FXE.

- Reminder of Friday afternoon gateway update.

XRO:

- Not present.

LAS:

- Nothing special to report.

UNSYS:

- Greasing the linear stages for undulators but not in SA2 (missing grease).

- SA1/SA2 after middle plane alignment UNSYS redefined the minimum gap and will be communicated through XO.

- Cell#36/SA2 there is a cable disconnected that need to be fixed.

- SA1/SA2 working with PS tables for extending operating tables for higher photon energies.

SPB:

- Work with EEE changing all the crates (Beckhoff)

FXE:

- Nothing to add

MID:

- Several ongoing infrastructure works are going fine.

- Worried with Beckhoff fuses (reported two years ago by Konstantin). It will be good to hear experience with SPB.

HED:

- Nothing to add

SCS:

- Nothing to add

SQS:

- Nothing to add

General Announcement:
- Another cryo failure happened yesterday night due to an overpressure. Expected cryo OK shall be around 10AM. Plan to tune today holds.
- Steffen H. reminds that instruments shall participate in the Jour-fixe today at 13:00.

CTRL:
- Nothing to report.

DA:
- Announcement from the calibration team: offline calibration will have a deploy today – minor intervention – to correct e.g. bug fixes

EEE:
- SA3 PPL has a card that behaves not normally. Needs an access and is been repaired right now.
- Pouhneh S. says that Saturday reason maybe be related to laser interlock. The whole SA3 went down. Lasermet was onsite and a wire was shorted circuit. Needs to look closely if it was interlock . 
It acted as if the emergency OFF was pressed. Zunaira A. says that this happened also in SA2 time ago: AMPHOS shutter has a sub-D connector and when this connects the fuse blows and power went down; LAS 
and Klaus Witt solved at the time and reason shall be related to the AMPHOS shutter. 
K. Wrona says as DRC he has got a call informing the power glitch. This morning the network switches in the room are still not functioning. Please call DRC using DOC number when power goes down.

VAC:
- Nothing to report.

XPD:
- Nothing to report.
- On the power glitch of SA3: only SQS and SCS hutch devices were affected by the power glitch due to the short circuit on the interlock/PPL.
- Switch to the 18keV in SA2 went smooth on Saturday.

DET:
- AGIPD in SPB showed radiation damage. On May 7th the detector was exposed to high radiation and investigation still ongoing. 
About 10% of pixels are damaged and need full characterization to find if still usable for users.

ITDM: 
- Nothing to report.

XRO:
- Last week on Friday: moved Mirrors M1 and M2 of SA2. Mirror positions seem to be in the right positions. 
When beam is handled over to MID the XRO group has to check alignment and it is already agreed with MID. Currently beam is in the Platinum stripe.

LAS:
- Power outage in SA3: seeder is back but interlock does not allow seeder shutter open (card to be changed). Many troubles with devices in the network.

UNSYS:
- ZZ for SA2/cell#2 to fix a problem.

SPB:
- Interesting program last week with stability investigation and beam usage on the weekend.

FXE:
- Got support from Data calibration: thanks!

MID:
- All fine at MID.
- Ulrike B. comments on the Karabo broker pile up over Easter: noticed now that there is a mismatch between what is written and triggered. 
Wajid E. says that will contact offline to MID to further understand. It is corrected as of now. Bruno F. says that there is a ticket ongoing (wrong timer connection affecting the configuration location).

HED:
- Nothing to report.
- Long pulse train tests were successful and shall be used on cw22 - a meeting takes place with BKR today.

SCS:
- No full power outage in SCS hutch (beamline was checked and seem to be fine). XGM did not get interrupted.

SQS:
- Suffer from laser interlock during the weekend – could not take PP laser. Got a damaged scroll pump.
