Construction strategy of the GLAST tracker

The GLAST observatory is an astroparticle mission that will study γ-rays emissions from a wide range of cosmological sources in the 20 MeV-300 GeV energy band. The tracker is the largest (80 m2) silicon detector ever built for a space mission. Its construction is a major technological challenge which has required close collaboration of INFN with space qualified industries, in order to meet the requirements of reliability, high yield and large volume production.
