Simulation of the ILC Collimation System Using BDSIM, MARS15 and STRUCT

The simulation codes BDSIM, MARS15 and STRUCT are used to simulate in detail the collimation section of the International Linear Collider (ILC). A comparative study of the collimation system performance for the 250 × 250 GeV machine is conducted, and the key radiation loads are calculated. Results for the latest ILC designs are presented together with their implications for future design iterations. Presented at the 10 European Particle Accelerator Conference (EPAC 06) Edinburgh, Scotland, UK, 26-30 June, 2006 * Work supported in part by the British Council Alliance programme, the PPARC LC-ABD Collaboration, by the Commission of European Communities under the 6th Framework Programme Structuring the European Research Area, contract number RIDS-011899, by the Universities Research Association, Inc., under contract DE-AC02-76CH03000 with the U.
