Machine Protection Issues in the Beam Delivery System (LCC-0135)
This note reports on an EGS study of the collimation and protection devices contained within the TRC version of the NLC lattice. For each fault scenario, the likelihood for damage to collimators, spoilers, absorbers or magnet apertures is arrived at by finding the maximum energy density the device must support when a full NLC bunch train is lost on it or nearby it. We find that certain devices will not survive as currently specified. Modest design changes are recommended that should permit the system to operate up at 500 GeV center of mass energy; for 1 TeV operation, certain devices are still at risk.
