In order to prevent damage to accelerator components induced by various events, a global machine protection system (MPS) was installed and implemented. The MPS collect interlocks and beam dump requests from various system (thermo/flow of magnets, front-end, vacuum system, and orbit excursion interlock), perform decision, transmit dump beam request to E-Gun or RF system. The PLC based system with embedded EPICS IOC was used as a slow MPS which can delivery less than 8 msec reaction time. The fast MPS was dependent on event based timing system to deliver response time less than 5 μs. Trigger signal for post-mortem will also be distributed by the fast MPS. To ensure alive of the system, several self-diagnostics mechanisms include heartbeat and transient capture were implemented and tested. The MPS architecture, installation, and validation test results were presented in this report.
