Idea is to test the noise reduction from the 50Kz Mains line and test if one can run without this sync with the 50Hz in future. If things run fine during the test one would run for two days without this 
Synchronization.

CTRL proposes to apply to all other location today. No objections from the instruments appear during this meeting - so it will take place today.

DA:
- Nothing to report.

EEE:
- Nothing to report.

VAC:
- XTD6 was opened today for work on the high resolution Mono. It will stay open at least today and tomorrow.
- On Saturday VAC OCD approved to borrow a He bottle to MID. MID will return back to VAC today for He leak tests in tunnels.

XPD:
- Nothing to report.

DET:
- Nothing major to report.

ITDM: 
- Nothing to report.

XRO:
- Mikako M. enquires on the Blue week schedule: A. Galler says that requesters that got beamtime granted must be informed already.

LAS:
- SA1 PP-laser will test the trigger delay;
- LAS is performing SA3 PPL tuning for handling laser to SQS instruments.
- A. Galler says that optical sync was lost during the weekend in all instruments. The RF sync was on 30fs RMS performance which could be used.
UNSYS:
- Request for access in SA3 was done (fixing PS motors in cell 20 and 21): mostly to be done tomorrow or Wednesday.

SPB:
- Nothing to report.

FXE:
- PP-laser sync problems (6x last week) with loosing timing. It put the PPODL device into Error state; it could be recovered automatically but the laser timing wasn't conserved. 
So in about half the events the laser timing changed by 2-5 ns. Ticket was placed.

MID:
- Thanks to VAC for borrowing He bottle.
- Problems with optical sync; otherwise all fine.

HED:
- Nothing major to report.

SCS:
- Issues with Optical sync: drop happening on the Desy side (which do not have OCD on the weekend). After loosing Sync it took long to recover synchronization. At total about 15hs of beamtime was lost.
- There is no good alarm system indicating the sync was lost. This can be addressed at EuXFEL side. Steffen H. adds that a ticket is ongoing now and a good way for displaying will be worked out.

SQS:
- Nothing to report.

General Announcement:
- M. Doering announces on the LIMP-25: 
1. XTD10 Scaffolding is installed for cabling work in October; 
2. PLC updates: remaining work in tunnels to be done next week (discussed with VAC and XPD) as well as at SQS; 
3. Update task list: M. Doering will send to the groups the Task list for that it is updated accordingly to the latest status (e.g. completed, cancelled, delayed...); 
4. Recurring tasks for the Winter Maintenance will be planned for the end of the year. A list will be sent to the groups and please inform XO if you have new activities to be done before 2026. 

CTRL:
- Karabo upgrade: start with MID next week to spot possible issues. MID topic will be accessible from the hutch only. 

DA:
- Nothing to report.

EEE:
- PLC updates: see above.

VAC:
- Everything progressing well in XTD6 also with PLCs. 

XPD:
- Nothing to report.
