A high resolution wide range photon tagging system
Abstract
A photon tagging array which measures the energy of photons in a bremsstrahlung spectrum is described. The apparatus covers an energy range of 1600 MeV starting 250 MeV below the energy of the incident electron beam. Sixty-four tagged channels provide a theoretical resolution of ±12.5MeV and measurements indicate the overall resolution, using a {1}/{100} radiation length radiator, to be better than ±17.5MeV. Design and constructional features are incorporated which permit considerable reductions in the installation, survey and monitoring requirements.
