Material Damage Test with 450 GeV LHC-Type Beam

The design of LHC protection elements is based on assumptions on damage levels, which are derived from simulations. A dedicated experiment was carried out to cross-check the validity of this approach by trying to damage material in a controlled way with beam. The impact of a 450 GeV beam extracted from the SPS on a specially designed high-Z target with a simple geometry, comprising several typical materials used for LHC equipment, was simulated. The beam intensities for the test were chosen to exceed the damage limits of parts of the target. Results of the simulations are presented and compared with test results.
