In HI-13 Tandem Accelerator laboratory, a new radiation protection system has been built Which composed of 7 protective door control units and 7 emergency alarms , 23 groups of indicators,17 groups of workshop-empty units , L.E and IMAG Faraday cups as well as computer control and display system . Pre-empty process is prerequisite before close the protective doors to ensure nobody be exposed on irradiation environment otherwise the door-open would be disabled. Even thought somebody left, pushing nearby alarm button and emergency door-open button will induce glittery signal and simultaneous door-openning. L.E and IMAG Faraday cups execute immediate beam interruption once accidence occured . The distributed indicators indicate real time status of all the work fields. All above devices and units are interlocked follow some complex but logical protective rules. Computer workstation is built and accordingly, after full information and operation action signals are collected and transferred, the software can complete full-sides status monitoring, provide convenient control and display interfaces as well as pop adequate prompt frames.
