We describe a novel multi-GeV photon detector which operates under an intense flux of neutrons. It is composed of lead–aerogel sandwich counter modules. Its salient features are high photon detection efficiency and blindness to neutrons. Monte Carlo (MC) simulations show that the efficiency for photons with energy larger than 1GeV is expected to be higher than 99.5% and that for 2 GeV/c neutr…
