Status of the Engineering Array of LHAASO-WCDA
Abstract
A Large High Altitude Air Shower Observatory(LHAASO) is proposed and to be built in next few years. The Water Cerenkov Detector Array(WCDA) plays an important role in the LHAASO project. An engineering array at 1% scale(3 x 3=9cells) of WCDA was constructed at YangBaJing in 2011. With the help of it, the relevant techniques, such as the waterproof potting of PMT, the counting rate, the light shielding, the water quality control, the data analysis, the engineering issues and so on, are well studied and to be presented in this paper. Furthermore, the combined analysis between the engineering array and ARGO-YBJ experiment has also been studied. This work will offer a great help for the future operation of the full array.
