作为LHAASO项目的主要组成部分之一,将在中国西藏羊八井建造一个约8万m2的水切伦科夫探测器阵列(WCDA)。它的主要物理目标是在天空中寻找能量范围为100 GeV - 30 TeV的伽马射线源。简要介绍了该阵列的技术设计细节,包括阵列的结构、定标系统的设置、电子学和数据采集系统的规格,并研究和报道了该阵列在伽玛天文学的几个方面的性能,特别是在观测河外耀斑方面的性能。
As one of major components of the LHAASO Project, A Water Cherenkov Detector Array (WCDA) of size about 80000 m 2 is to be built in Yang-Ba-Jing, Tibet, China. The main physics target of it is to survey the sky for Gamma ray sources at the energy range 100 GeV – 30 TeV. Technical design details, including the configuration of the array, the setup of calibration systems, the specification of electronics and DAQ system, are briefly introduced; the performance of the array on several aspects of Gamma astronomy, especially on surveying extragalactic flares, are studied and reported.
