	J-Parc linac has developed the output beam power by increasing of acceleration energy and the peak beam current. The beam loss is getting serious along with increasing the output beam power, however, the beam loss caused at the low energy part is difficult to detect due to the low energy radioactive emission. An interlock system has been developed to prevent from the sufficient material activation using the beam current monitors. In the system, an electrical circuit to take the beam transmission between two beam current monitors is newly designed and fabricated. This paper describes the performance of the electrical circuit and the system configuration will be introduced.

	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.

	Design, implementation and setup of a FPGA and RocketIO based FPS(Fast Protection System) for CSNS(China Spallation Neutron Source) is introduced. This system is a compact design with high speed serial transmission techniques. RocketIOs (or MGTs) and optical transceivers are used to transmit the interlock signals, with each link to carry 16 signals. Ground loop problems are avoided since the use of fibers. Dedicated firmware is developed for the auto-working of the serial links when both fibers are plugged in under power-on state. A real-time online heart-beat function is also implemented for each interlock signal to make sure the overall safety of the system. The whole system is under installation and will be put into use soon part by part according to the progress of the civil construction and equipment installation.
