Abstract

The subsystems of a particle accelerator must be turned on in a proper sequence to perform successful beam acceleration. Furthermore, the charged particles must interact with the RF fields (or the laser fields in case of laser-plasma acceleration is used) at the correct time for the desired accelerating phase. The timing and synchronization systems guarantee the required timing relations between the RF fields and the beam. The timing system defines the timing events and produces triggers if required for different subsystems to start or stop their operation. The synchronization system provides a common frequency and phase reference to all subsystems. We will introduce the basic concepts and architecture of the timing and synchronization systems in this chapter.
