Cosmic ray test of BC408 and HpGe coincidence

5:00 pm started overnight coincidence run file name jun21_2007_background002

jun21_2007_background002 was stopped at 11:12 am on June, 22

Lead bricks with thickness of 10.4 cm were used as a shielding for HpGe detector on the both sides, front layer was 20.4 cm and bottom one 5 cm. The was not lead on top of HpGe detector


1. The ungated cosmic ray spectrum obtained from HpGe detector

2.Cosmic ray spectrum detected in fast plastic scintillator BC408

Example21.jpg


3.Spectrum of time intervals between signals coming from germanium detector and fast plastic scintillator
