General Announcement:
- Regarding Operation, VAC and PRC had a workaround to restore the North branch beam permission on Sunday.
- XTD9 Turnstiles were not working this morning for ZZ access planned by FXE.
During the meeting we heard the information that Michael Prollius / SRP has fixed it by rebooting the computer.
CTRL:
- Since Wednesday CTRL had one OCD call regarding the SA3/GATT gauges and controller configuration.
- SQS server - issues with interactions. Work ongoing.
- INFLUX roll out: test on CAS monitor topic is successful. For the double loggers, there will be an impact of 5-10 minutes down time when login.
This will happen on FXE (2x10min without data): it is OK for FXE and for LAS today. IF that is successful, CTRL will contact other instruments.
DA:
- Nothing to report
EEE:
- It has been working on the follow-up of HED topics.
- EEE OCD had a call on the SA3/GATT gauge controller.
VAC:
- Severe trouble with SA3 GATT: damage on the gauge controllers was a result of series of problems.
- Bearing of a downstream booster pump make vibration and developed two leaks; then pressure went bad;
vacuum gauges showed wrong numbers and resulting in electronic damage in the controller cards.
- The booster pump was exchanged on Friday; on Sunday a leak test found a broken vacuum welding and part was removed.
Currently ZM3 at Desy is fixing it. Expected to be ready for tunnel installation by 10AM.
- Sunday from 13:00: the GATT was in UHV mode to allow beam permission and lasing in SA1 and SA3 up to Monday 6AM.
- Currently XTD10 is open for GATT repair and PES exchange of turbo pump.
