Description

A rotatable collimator as developed at SLAC for NLC was proposed for LHC’s Phase II upgrade to provide a low impedance metal collimator, able to recover from several damaging hits by the beam. This talk reviews the technical problems involved, the FLUKA/ANSYS simulations which have guided our design decisions and the materials considered for the jaws. It focuses on the the reasons for the choice of Glidcop, copper and molybdenum for the jaws and the ongoing material issues relating to the jaws and ancillary components.
