The Synchrotron Motion Simulator for Adiabatic Capture Study in the TLS Booster

Abstract

The synchrotron motion simulator is invented to simulate the longitudinal motion for particles under RF (Radio Frequency) voltage field in a ring accelerator. It is especially used to study the efficiency of adiabatic capture for a booster ring. The purpose of adiabatic capture is to optimize RF voltage settings during the ramping of beam energy and obtain the greatest efficiency of particle capture. In this paper we study the longitudinal (synchrotron) motion for particles in the TLS (Taiwan Light Source) booster. We compare the properties of TLS booster as a proton or electron accelerator, using the same ramping scenario of beam energy, and optimize the RF voltage settings to have the best capture efficiency.
