AGATE: Expanding on the Success of EGRET

The Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Observatory has increased our understanding of active galactic nuclei, pulsars, diffuse emission, solar flares and gamma ray bursts. In order to continue these advances in high energy gamma-ray astronomy, development of a follow-on telescope to EGRET is in progress. The new experiment, named the Advanced Gamma-Ray Astronomy Telescope Experiment (AGATE), has the same basic components which have made EGRET a successful, low background telescope for 30 MeV to 30 GeV gamma rays; however, the sensitivity has been increased by an order of magnitude, the energy range extended to higher energies, and the angular resolution improved.
