A system, which monitors the timing offset values of fast timing and the linearlity of responces of the scintillation counters used for the observation of cosmic ray air showers, are developed and connected to the air shower array of Mt. Norikura. The monitoring system is composed of a generator of nitrogen gas pulse laser, an attenuation unit to regurate the light intensity, optical fiber cables to deliver the light pulses to each scintillation counter, and a micro-computer to automatically oparate the system. The timing offset value and its dependence on light intensity are monitored with a accuracy of 0.13ns of error. The linearity curve of scintillation counters was checked for the range of three order of light intensity. This system will offer a high resoluving power for the detection of incident direction of cosmic ultra high energy gamma rays.

开发了一种系统，该系统可监测用于观测宇宙射线气簇的闪烁计数器的快速计时的计时偏移值和响应线​​性度，并将其连接到乘鞍山的气簇阵列。监测系统由氮气脉冲激光发生器、调节光强度的衰减单元、将光脉冲传送到每个闪烁计数器的光纤电缆以及自动操作系统的微型计算机组成。定时偏移值及其对光强度的依赖性以 0.13ns 的误差精度进行监控。在三个数量级的光强范围内检查闪烁计数器的线性曲线。该系统将为探测宇宙超高能伽马射线的入射方向提供高分辨率。
