e-ASTROGAM is a proposed space mission with the purpose of measuring gamma-rays from astrophysical sources in the energy range from 300 keV to a few GeV. Its proposal has been submitted in 2016 within the ESA M5 Call. e-ASTROGAM reaches a sensitivity one-two orders of magnitude larger than its predecessor, the detector COMPTEL on the Compton Gamma Ray Observatory (CGRO), and offers as a new feature the capability of fast triggers for astrophysical transients.
e-ASTROGAM is made of 56 Silicon planes, about 1 m^2 each, which record Compton interactions and pair production events induced by cosmic photons, by an anticoincidence detector and by a calorimeter.
The international collaboration working to e-ASTROGAM involves scientists working in institutions from Denmark, Ireland, Italy, France, Germany, Japan, Poland, Portugal, Russia, Spain, Sweden, Switzerland, United States.
