A laser calibration system was developed for monitoring and calibrating time of flight (TOF) scintillating detector arrays. The system includes setups for both small- and large-scale scintillator arrays. Following test-bench characterization, the laser system was recently commissioned in experimental Hall B at the Thomas Jefferson National Accelerator Facility for use on the new Backward Angle Neutron Detector (BAND) scintillator array. The system successfully provided time walk corrections, absolute time calibration, and TOF drift correction for the scintillators in BAND. This showcases the general applicability of the system for use on high-precision TOF detectors.

开发了一种激光校准系统，用于监视和校准飞行时间（TOF）闪烁探测器阵列。该系统包括用于小型和大型闪烁体阵列的设置。经过测试台的表征，该激光系统最近在托马斯·杰斐逊国家加速器设施的实验厅B进行了调试，用于新型后角中子探测器（BAND）闪烁体阵列。系统成功为BAND中的闪烁体提供了时间步长校正，绝对时间校准和TOF漂移校正。这展示了该系统在高精度TOF检测器上使用的一般适用性。
