MEGA

Medium Energy Gamma-ray Astronomy

MEGA would be an imaging system for gamma rays in the energy range of 0.5 MeV to 50 MeV. The instrument takes advantage of the Compton effect and pair production events. An incident gamma photon undergoes Compton scattering in a first detector. Here the photon looses energy and changes its direction of motion. After the first interaction, the photon will be stopped in the second detector made of several modules of Cesium Iodide calorimeters.

MPE Participation:

  • The prototype of the instrument was designed and built at MPE
