Circuit forms gamma photon detector: 04/24/03  EDN-Design Ideas / (Electronic circuit added 10/03) The circuit of Figure 1 includes a PIN photodiode that detects individual photons of gamma radiation. The reverse bias on the photodiode sometimes creates a depletion region. When such a photon strikes this depletion region, a small amount of charge develops. This charge is proportional to the photon's energy...
