Coherent synchrotron radiation effect mitigation studies for high brightness beams/accelerators
Abstract/Contents
- Abstract
- Many particle accelerator applications today call for high-brightness electron beams. In this dissertation, research is described on the mechanisms driving self-radiating forces arising from high-brightness beam environments and the mitigation of such forces. In the first half of the dissertation, we will focus on quantifying the Coherent Synchrotron Radiation (CSR) Effect for various accelerator scenarios. New expressions for the CSR RMS energy spread are developed for transient regime with and without bunch compression and for the subsequent drift section after a bend. The expressions are rigorously tested with the particle tracking codes ELEGANT and CSRTrack [14, 15]. In the latter half, we will take a particular focus on the final-stage bunch compression systems of linacs for X-ray free-electron lasers (XFEL), where these self-forces are prevalent, and introduce a new bunch compressor chicane design: the 5-Bend chicane. The new chicane's performance is compared versus a standard 4-Bend chicane in terms of emittance preservation and XFEL performance in a comprehensive simulation study. Though the work presented here pertains to the XFEL linac environment, the physics and techniques can be applied to any sort of accelerator involving high-peak current, low-emittance charged particle beams
