Description

The Large High Altitude Air Shower Observatory (LHAASO) project is to be built at Daocheng, Sichuan Province, 4400 m a.s.l., in a few years. As one of the major components of the LHAASO project, LHAASO-WCDA, a water Cherenkov detector array with an area of 90000 m2, contains around 400,000 tons of purified water. To gain full knowledge of the water Cherenkov technique and to investigate the engineering issues, a 9-cell detector array has been built at the Yang-Ba-Jing site. With the array, a method of water quality monitoring and measurement with cosmic muon signals is studied, whose results show that a precision at some ten percentages can be achieved, satisfying the requirement of the experiment. The results are compared with those from a full Monte Carlo simulation. This method is proposed to be applied in the LHAASO-WCDA project.
