Space detectors for gamma rays (100 MeV-100 GeV): From EGRET to Fermi LAT
Abstract
The design of spaceborne high-energy (E > 100MeV) γ-ray detectors depends on two principal factors: (1) the basic physics of detecting and measuring the properties of the γ rays; and (2) the constraints of operating such a detector in space for an extended period. Improvements in technology have enabled major advances in detector performance, as illustrated by two successful instruments, EGRET on the Compton Gamma Ray Observatory and LAT on the Fermi Gamma-ray Space Telescope.
