Abstract
In this study, the detection of cosmic ray from the earth’s atmosphere is addressed. The speed and the lifetime of the muons are measured with plastic scintillator coupled to photomultiplier detector. In this research, the digital system is used over the analog system due to its reliability, high speed performance, small volume, and accurate response. We find that the mean speed of muons to be around ( 2.831 ± 0.0394) *108 m/s ,(β = 0.944 ± 0.0131), with the mean lifetime of 2.033 ± 0.177 microsecond which are consistent with the theoretical results. In this experiment, we use the facilities at the School of Particles and Accelerator in IPM.
