Abstract

A cosmic ray hodoscope with two-dimensional spacial sensitivity and good time resolution has been developed. The system is designed to use the cosmic muons as probes to test the performances of charged particle sensitive detectors. This paper will present the structure of this system, the timing calibration and the resulted performance of this system. The results of the test of the prototype electron detector for LHAASO project are presented as well.
