Welcome to the web site of the LHC Collimation Upgrade Specification 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.

Latest developments

New updates to the halo simulations page: fast dump failures, 4 TeV quench test with updated carbon density, DS collimators.

WP5/HiLumi page: added D5.4, D5.5 and MS51.

List of deliverables and milestones of WP11 added to EuCARD2 page.

All images should be clickable now. Send us an email if you find a bug or a dead link!
