Cutting Beam Horns in BC1

Cutting Beam Horns in BC1. Paul Emma, Josef Frisch. Why and what. In LCLS compression system tails on the beam are folded over by longitudinal wakefields and produce high peak current spikes on the ends of the bunch The high current spikes cause CSR emittance growth

Results with initial collimation (July 18, 2007)

Results with initial collimation (July 18, 2007). F. Zhou, 8/8. Further collimation optimization. To collimate particles beyond transverse acceptance, two ways: One straight way is to add betatron collimators before the system end but the power loss at 5 GeV is larger.

Present Approach and Status

Present Approach and Status. R. Assmann for the LHC Collimation Team. Problem: Al/Cu system would not resist irregular dumps (pre-trigger or asynchronous) and low beam lifetimes, even during early physics. Solution: Low Z material: More robust but longer.
