Abstract

A charged particle detector with 0.7 sr solid angular acceptance has been built, principally to detect protons in the energy range 25–150 MeV in experiments with tagged photon beams. The detector consists of a three element ΔE1−ΔE2−E plastic scintillator telescope. Position information is obtained from the time difference between signals from the two ends of each scintillator. The design of the detector and tests of its performance are described. An energy resolution of 2.8 MeV fwhm at 60 MeV proton energy, and a two-dimensional position resolution of 24 mm × 41 mm fwhm has been obtained. Successful operation in the tagged photon environment is demonstrated.
