Title: Start-to-end Transport Design and Multi-particle Tracking for the ILC Electron Source

Abstract

A train of 2-ns micro bunches of longitudinally polarized electrons are generated in a 120-kV DC-gun based injector in the ILC electron source; a bunching system with extremely high bunching efficiency to compress the micro-bunch down to 20 ps FWHM is designed. Complete optics to transport the electron bunch to the entrance of the 5-GeV damping ring injection line is developed. Start-to-end multi-particle tracking through the beamline is performed including the bunching system, pre-acceleration, chicane, 5-GeV superconducting booster linac, spin rotators and energy compressor. It shows that 94% of the electrons from the DC-gun are captured within the damping ring 6-D acceptance--A{sub x} + A{sub y} {le} 0.09 m and {Delta}E x {Delta}z {le} ({+-} 25 MeV) x ({+-} 3.46 cm)--at the entrance of the damping ring injection line. The field and alignment errors and orbit correction are analyzed.
