A timing system was constructed for Accelerator Test Facility(ATF) for future linear collider R&D at KEK. The operation of the ATF has several features, for example, multi-bunch acceleration, delta-f energy compensation, multi-train storage, etc.. The timing system provides synchronized reference signals and trigger signals for each hardware. To keep stable phase relationships at each component...
