Abstract

In order to investigate the longitudinal beam dynamics during the adiabatic capture and acceleration processes of the CRing in HIAF project, a simulation of both processes above is carried out with $U^{34+}$ ions. The ions will be captured into a bucket adiabatically and accelerated from 800 MeV/u to 1130 MeV/u . Simulation of these processes by tracking appropriate distributions with the longitudinal beam dynamics code ESME has been used to find optimum parameters such as RF phase, RF voltage and RF frequency etc. An enhanced capture and acceleration efficiency can be gotten from the simulation results, with the optimized RF voltage and RF phase program.
