Location: General 
Severity: Information 
Subject: Notes XO Integration Meeting 17.05.2021 
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:
- Nothing to report.

XPD:
- Nothing to report.

DET:
- Incident at SPB with AGIPD detector: damage to several pixels. The cause for it is not yet known. 
The pixel modules have the replaced and the cause relates to intense radiation. It's important to follow up and understand how it happens. SPB will investigate and 
communicate findings.

ITDM: 
- Nothing to report.

XRO:
- Nothing to report.

LAS:
- Everything good with Lasers.

UNSYS:
- Issue with Quad mover in cell18/SA1 - Suren A. could address it without need of access but further investigations have to be done on-site.

SPB:
- Small injection incident over the weekend.
- Problem with one DAQ: number of pulses was OK but not the values. This was solved by the DOC and some data were wrongly saved for the users (attenuation values).

FXE:
- Timing tool tests at FXE during the night: crosstalk between SA1/SA3. When number of SA1 bunches were changed, the beam pointing was changing in SA3. 
So FXE was requested to do not change bunch numbers what hindered the tests.
- LPD issue: progress has been made last week and is being accelerated.

MID:
- Quick warning: until Wednesday some Seeding tests will be ongoing at MID.

HED:
- Successfully experiment last week: HED thank all involved people.
- Addressing CTRL deployment: HED will contact CTRL after this meeting to discuss some details before the deployment action goes on.
- On last Friday at 13:00 one camera corrected configurated did not acquire data and DOC was contacted.
- On Saturday the timing drifted linearly for 0.5ps. HED contacted PRC and DRC and is not yet completely understood.

SCS:
- Nothing to report.

SQS:
- Confirm what FXE has said on the crosstalk with SA1/SA3.
- Sometimes MCP detector was inserted and trigger the EPS to beam stop. Jan G. says that there was a mistake in the interlock configurations for going above 30 bunches.
When SQS wanted to go to 67 bunches it triggered the beam OFF.
