怀柔EAS阵列的方向测定系统

The Direction Measurement System of HuairouEAS Array

本文介绍了由9路快时间测定通道构成的怀柔EAS阵列方向测定系统的测定原理、设备组成,描述了它的标定和使用方法,讨论了它的时间和方向测定精度。光脉冲模拟测量给出通道的分辨时间不大于1ns,对实际观测事例的统计分析表明,系统对EAS的时间分辨约为3ns。该系统已连续运行约一年,并产生了首批物理结果。

In this article we describe a direction measurement system consisting of 9 FT channels in Huairou EAS array. The principle of measurement, the components of system, the calibration and operation methods are presented. The accuracy of time and direction measurements are discussed.The time resolution measured by light pulses is near 1 ns, time resolution of system for EAS particles extracted from EAS events is about 3 ns.This system has been running for one year and some physical results are coming out.
