Beam offset impact on the polarization in the CLIC beam delivery system

Abstract

The baseline configuration of the Compact Linear Collider (CLIC) foresees an electron beam with 80% polarization at the interaction point (IP) to be measured with an accuracy of 0.1%. The propagation of the polarization through the CLIC beam delivery system (BDS) is investigated here using the BMAD code. The impact of offsets applied both to the beam and the different elements in the CLIC BDS on the polarization at the IP is evaluated.
