Contact the scientific secretary if you want to be added to the mailing list and/or propose a topic for the next meeting.

Study beam dynamics and operational aspects of new collimation schemes in the dispersion suppressors of the insertion regions of the LHC, for upgrade scenarios beyond LS1.
Identify open issues and assign priorities to the work required and provide the necessary inputs to the team involved, including external collaborators.

Next Meeting: 7 June 2022 at 4.00pm - ColUSM virtual room
