摘要
Abstract
In high-current accelerators,anomalies in the Marx self-excitation of the pulsed-power system and in the loading of the magnet-excitation power-supply can degrade experimental quality or even cause the experiment to fail.A machine-protection system is presented,which is built around a Compact Reconfigurable Input/Output(CRIO)controller that continuously monitors Marx discharges and magnet-power-supply loading to provide fast machine protection.It simultaneously communicate with the accelerator's central control system,which is based on the Experimental Physics and Industrial Control System(EPICS)architecture.A Field Programmable Gate Array(FPGA)module inside the CRIO guarantees the response speed of the fast-protection logic,and a Real-Time(RT)module acts as an Input/Output Controller(IOC)within the EPICS framework,subscribing to and publishing EPICS process variables to achieve seamless integration across heterogeneous platforms.The system exhibits strong immunity to interference;since commissioning it has operated reliably in the accelerator's complex electromagnetic environment,significantly improving the experimental reliability.关键词
