Abstract

Copyright © 2015 CC-BY-3.0 and by the respective authors.Different types of electron bunch compression schemes are compared for the AXXS FEL design study. The main linac for the proposed machine is based on CLIC x-band structures. This choice leaves several options for the bunch compression schemes which impact the injection system RF band. Both harmonic linearization and phase modulation linearization are considered and their relative strengths and weaknesses compared. Simulations were performed to compare the performance of an s-band injector with a higher harmonic RF linearization to an entirely x-band injector and linearization scheme. One motivation for the study is to optimize the length of the AXXS machine, allowing the linac to fit onto the proposed site and also act as the injector to the existing storage ring at the Australian Synchrotron.
