BEAM-BASED FEEDBACK SYSTEM FOR THE INTERNATIONAL LINEAR COLLIDER

摘要

The algorithms and computer codes for linac Feedback system were developed atSLAC during 1991-2004. The efficiency of that system have been demonstrated for the SLC, CLIC, TESLA and NLC projects. International Linear Collider (ILC) has its own fea_tures. Ground motion (GM) oscillations play a dominant role here. It forced to implement a new version of the Linac Feedback Simulation Code based on the previous develop_ments. A set of benchmark tests and realistic simulations for the whole ILC structure have been performed. The effects of different GM models, BPM resolution, time inter_vals, initial misalignments, a dispersion-free steering (DES), and a quad jitter have been studied.
