【摘要】 光刻度系统是中子墙探测器系统的重要组成部分,用于中子墙前端电子学的刻度和探测器工作性能变化的监测．通过对基于发光二极管(LED)作为光源的中子墙光刻度系统方案开展了细致的测试研究,确定了基于快脉冲驱动的大功率蓝光LED(3W)的中子墙光刻度系统方案,对中子墙探测单元进行了初步刻度测试,刻度结果能很好地满足光刻度要求,表明对于快塑料闪烁体探测器该方案是一种较为理想的方案．更多还原

【Abstract】 The light calibration system is one of the key components of Neutron Wall detector.It is used to calibrate the electronics and to monitor the long-term stability of the detector modules.With the detaile investigations,a calibration system with high-power LED(3W)driven by the fast pulses has been carried out.It is also tested together with the detector module of the Neutron Wall and the result of the preliminary calibration demonstrates that it fulfills the needs. It’s a new design proposal to the light calibration system of the fast scintillator detector.更多还原
