Speaker: Martin Barisits (CERN)

2022 LHC schedule

• During data taking we tried to align Rucio feature releases with technical stops
  • Actual physics run will start in August 2022 (Relatively late)
• If we aim for a 3 release model again I would suggest
  • 1.28 March 2022
  • 1.29 LTS July 2022 (To be deployed well before Jul 25 run start)
  • 1.30 November 2022 (To be deployed during MD3/TS2 window)
• Release names
  • Got some good suggestions
  • Will start a vote today/tomorrow
