- XO thanks the groups who have already sent the maintenance lists. For the remaining groups, please contact at the xo-planning@xfel.eu.

CTRL:
- Few minor OCD calls during the weekend: One relates to a camera triggering.
- Issue with SA3 vacuum loop seems to be currently fixed but needs further investigations.
- Update of Beckhoff motors is planned for this week. CTRL will get in touch with Instruments.

DA:
- Nothing special to report.

EEE:
- Nothing to report.
- Question to XO on Maintenance: Could we have a draft of tasks list before Nov. 6th? 
Andreas G. answers that XO is working on it and as soon as lists are finished this will be published. In case info on partial parts is already needed, may be provided 
depending on the progress.

VAC:
- SA3 vacuum loop issue was mentioned by CTRL (see above).

XPD:
- Nothing to report.

DET:
- Nothing special to report.

ITDM: 
- Update will be done on DA acquisition of HED. This has been communicated with instrument personnel.

XRO:
- No bad news to report.

LAS:
- SA3 PP-laser presents small power drop in the laser beam: LAS will take care this week.
- SA1 PP-laser has a problem with ADC and stop acquiring data.
- Need to update firmware of ADC cards to get train ID's in SA3 PP-laser. This was requested to EEE. This may bring laser down again and may not be ready by Thursday. XO, 
LAS and EEE will discuss offline. 

UNSYS:
- Nothing to report.

SPB:
- Last week was smooth.

FXE:
- Problems with tunnels last night at around 1:00AM. More than half the shift was lost with no beam delivery: main user data was therefore not acquired. 

MID:
- Nothing to report.

HED:
- Beam was lost between 1AM to 7AM. Last data has been taken between 8:00 and 9:00AM. 
- During the weekend, beam drift was observed at Pop-in at the end of the tunnel. There are data and has to be analyzed.
- Discussion on implementation of Dynamic trigger will take place.

SCS:
- Not present.

SQS:
- Minor issue with Data: one data aggregator was not working properly. OCD and SQS personnel have solved it. 
K. Wrona comments that too many properties overloaded the aggregator. A long term solution will be worked on.

General Announcement:
- General announcement: reminder that on September 30th is the deadline to submit the winter maintenance task list. Tasks that are announced later may be included but it cannot be guaranteed to be 
scheduled in the planning.

CTRL:
- Nothing major to report.

DA:
- Nothing to report.

EEE:
- Update in SA3 EPS taking place today to add the SXP imagers.

VAC:
- ZZs taking place last Thursday to bring up VAC signal to North branch: currently looking into causes of XTD2 hiccups.

XPD:
- Thursday event with issues with hard X-ray PES: one channel for the digitizer saw an increased noise; also the MPODS that supply voltages did not restart and a ZZ is necessary to be brought the PES 
operational again.
- Another ZZ is requested by Naresh K. in XTD6. This is scheduled for today.

DET:
- Nothing to report.

ITDM: 
- Issue with loading of calibration factors taking long time: it did not happen again.

XRO:
- Nothing to report. As PRC Maurizio V. reported a quiet weekend.

LAS:
- Nothing to report.

UNSYS:
- Friday cell 12/SA3 phase shifter did not go below 11mm. If this is required again in the future one has to prepare working tables.

SPB:
- The 20keV operation was fine apart of the intensity slope trough the train. 

FXE:
- Nothing to report. No known issues with 12 keV operation on Friday.

MID:
- All fine at MID.

HED:
- Two user beamtimes were successful. 
- One hiccup was an issue with Cluster on Saturday night. That remain for 5-6 hours but was fixed by K. Wrona, who says that it is linked to the high number of created files. 
He increased it by a factor 10 to solve the issue. There are possibilities for improvements that will be discussed among HED, DA and ITDM. Similar experiment will happen again in two weeks.

SCS:
- Experiment taking place this week: electrical check ongoing and PLC connection also.

SQS:
- Nothing to report.

General Announcement:
- As DRC, Steffen Hauf reminds that if support from DA groups is needed, please request as soon as it is needed; Second: please instruments check if the Zoom is installed and running in the control rooms.

CTRL:
- Announcement: tomorrow around 13:00 a deploy of the new tag of Karabo is to happen in order to fix a bug on missing some devices in the topology.
