The control system consists of a timing and event distribution system, an EPICS based distributed run-time database and control system, and a comprehensive personnel and machine protection system. The timing and event distribution system defines the global system time frame as well as specific events that trigger local devices by an event generator and receiver framework, so that the time delay of each event could be controlled in 10ns resolution, and the timing jitter of trigger signal is below 0.1ns. The hard-real-time machine protection system is also integrated in the event system so that a fault event could be responded within 50 micro-seconds. Field control signals such as water temperature, vacuum, low level RF phase and amplitude and radiation dose are monitored and controlled via the EPICS database through Ethernet.
