Abstract
The GLAST satellite is a mission for the detection of gamma rays of both galactic and extra-galactic origin in the energy range 20 keV–300 GeV. The satellite is planned to be launched in 2007 by NASA. Gamma rays detection is based on the pair conversion mechanism achieved by a multilayer silicon strip detector interleaved with a tungsten target for photon conversion and e + –e − pairs tracking. The GLAST program did foresee a wide use of vibration tests both in development and in qualification phases. The acceptance phase in aerospace environment is usually demanding in terms of vibration tests. Furthermore in this program the trays’ design and manufacturing procedure might have been highly vibration sensitive, and experimental validation was considered highly recommendable. This paper aims to give evidence of the performed tests. A critical analysis of the tests is proposed and some results will be also presented.
