Abstract :
We have performed particle tracking simulation of J- PARC RCS to study the synchronization process. A frequency offset is added to the original rf frequency pattern to shift the bunch center, under the condition that the offset value should be ´adiabatic´ with respect to the synchrotron motion. Since the synchrotron frequency of the J-PARC RCS is substantially changed during acceleration, the particle tracking simulation helps to decide the limit of the frequency offset which can be employed.
