General Announcement:
- Announcement from Martin Doering on the next Winter maintenance period: 1. presented timeline for the coming WMP; 2. minor changes to the maintenance task list; 3. pre-announce the electrical 
interruption that will happen on Dec. 3rd;
- Release of MTL takes place in 02.09; deadline for submitting MTL on Sep.30th; release of summary task list on Oct. 28th. WMP starts on Nov.29th.
- Electrical Interruption on December 3rd: 
Two interventions to be done (by TS and MKK1) in order to connect power to XHO1 and XHV and to upgrade transformer at XHVAC (allowing uninterrupted maintenances in future). 
Affected locations: XHQ, XHEXP1, XHWS, XHVAC, media duct XHVAC and XHPSC; tunnels XTD4,6,7,8,9,10; XSDU-1 and XSDU-2. No power on 03/Dec. from 06:00 to 18:00. No access to campus during this time.
Ramp-down of equipment on 02.12 up to 24:00: all systems have to be powered off. 
Electrical work conducted on 03/12.
Ramp-up on Sunday 04 and Monday 05 December. Sunday is for critical devices that can not wait until Monday to be switched ON.

Safety choice is to power OFF all equipment, regardless of the secondary power line; Saturday is chosen as has the least overall impact at the facility and in working conditions.

G. says that if meeting can't be decided by Zoom, please send an e-mail to the task force with this enquire;

internally and let LAS known.

was ON from cell1-13. 
- Replacement of linear encoders are not possible with vacuum chamber between girders as needs alignment.
- First UNSYS will try to operate with rotatory encoders, if does not succeed, segments will be taken out.
- There are 4 spare encoders to repair 3 segments. Delivery time for new spares is 3-4 Months.
- Needs investigation to discover reason for the power outage in cells#14-23.
- Cell 33 in SA2 is fully operational.
