THE COSMIC RAY DATA ANALYSIS OF μ-COUNTER ARRAY IN BES

  • By analysing the cosmic ray data of μ-counter array in BES,we obtained informations on the threshold for identifying signal and noise,the detection efficiency of single wire layer,the particle detection efficiency,and the location resolutions in z direction and in γ-φ plane for μ-counter array.The comparison between eexperimental data and Monte-Carlo simulation showed good agreement.

Abstract: By analysing the cosmic ray data of μ-counter array in BES,we obtained informations on the threshold for identifying signal and noise,the detection efficiency of single wire layer,the particle detection efficiency,and the location resolutions in z direction and in γ-φ plane for μ-counter array.The comparison between eexperimental data and Monte-Carlo simulation showed good agreement.
