2019 July 22
The Water Cherenkov Detector Array (WCDA) is an important component of Large High Altitude Air Shower Observatory (LHAASO), which mainly aims at surveying the northern sky for VHE gamma ray sources. The WCDA has three pools with the area of 78,000 m2, and is sub-divided into 3,120 cells by black curtains. Currently, the installation of the first pool is already finished and normally operated. This paper will describe the preliminary results of the first pool and the optimized design of the two other pools.
