Improved Time of Flight gamma-Ray Telescope to Monitor Diffuse gamma-Ray in the Energy Range 5 MeV - 50 MeV

摘要

A time of flight measuring device is the basic triggering system of most of the medium and high energy gamma-ray telescopes. A simple gamma-ray telescope has been built in order to check in flight conditions the functionning of an advanced time of flight system. The technical ratings of the system will be described. This telescope has been flown twice with stratospheric balloons, its axis being oriented at various zenital directions. The results of these flights for what concern: diffuse gamma-rays, atmospheric secondaries, and various causes of noise in the 5 MeV-50 MeV energy range will be presented. (ERA citation 11:041428)
