Measurement of Cosmic Ray Flux in China JinPing underground Laboratory

Understand

China JinPing underground Laboratory (CJPL) is the deepest underground laboratory presently running in the world.

• In such a deep underground laboratory, the cosmic ray flux is a very important and necessary parameter for rare event experiments.
• A plastic scintillator telescope system has been set up to measure the cosmic ray flux.
• The performance of the telescope system has been studied using the cosmic ray on the ground laboratory near CJPL.
