	In this paper a new fast machine protection system is proposed. This system is designed for the injection Ι of C-ADS which fault reaction time requires less than 20us, and the one minute down time requires less than 7 times in a whole year. The system consist of one highly reliable control network based on a control board and some front IO sub-boards, and one nanosecond precision timing system using white rabbit protocol. The control board and front IO sub-board are redundant separately. The structure of the communication network is a combination structure of star and tree types which using the 2.5GHz optical fiber links the all nodes. This paper pioneered the use of nanosecond timing system based on the white rabbit protocol to determine the time and sequence of each system failure. Another advantage of the design is that it uses standard FMC and an easy extension structure which made the design is easy to use in a large accelerator.

The C-ADS Injector-I is an experimental proton machine in IHEP. An interlock system based on redundancy PLC was developed for machine protection and personnel safety. Device status, radiation dose, temperature of cavities and chambers are collected for machine state judge and interlock. A MPS (Machine Protection System) work together with the interlock system in the control loop, and protect the machine in four levels for different situation.
