With various requirements of machine protection system for accelerator facilities gathered from different labs, we jointly developed the Machine Interlock System (MIS). MIS has different hardware modules, including monitor modules, interlock logic calculating modules and I/O modules with various interfaces. In a global MIS network, different MIS crates could be interlinked over fiber network. The hardware of MIS utilizes FPGA rather than PLC for instantiation of interlock control logic. Therefore, the response time of <5 µs is achieved over a global MIS network. Another advantage of using FPGA is that multiple interlock modes could be realized and switched without hardware or software modification. Due to the two advantages above, MIS could satisfy different requirements of large-scale accelerator facilities. This paper presents the introduction of MIS and implementations in Shanghai Advanced Proton Therapy Facility and China initiative Accelerator Driven System.
