YETS schedule overview- main changes


CRG• CRG Sectors 78 and 81 will be emptied of Liquid Helium• Cryo back on the whole LHC machine on 4th March –

Sectors 34 and 45 some days before

BE-BI & VSC• BSRT replacement in LSS4 during W51• BWS change (ferrite) is not a baseline – could be done according to the evolution of the YETS

MSC• No intervention on ULO and No magnet exchange (sector 81)

EN-EL• Systematic inspection of Bus Bars to be realised – To be added in the schedule

ELQA• Investigations on the RCS is sector 78 can be realised in January, and the decision to realise ELQA before

the restart will be taken in Chamonix• If ELQA will be realised during HWC

Powering tests• Extension allocated - from 5th March to 16th March.

Some UPS tests included in this period.

Experiments• Readiness' of Atlas and CMS will be confirmed in Chamonix
