G004500100014 INC-SOURCE (BRST) 144 and 165 MeV electron beam to produce G004500100015 photons in the energy range of 65-115 MeV. G004500100016 (TAGD) Resolution of ~500 keV per channel and a G004500100017 mean flux of ~2E+6 /MeV/sec. G004500100018 Tagging efficiency was determined to be 44+/-1(sys)%. G004500100019 SAMPLE Liquid deuterium in a cylindrical cell (170 mm in G004500100020 length, 68 mm in diam.) made from 120 um Kapton foil. G004500100021 The target was (8.10+/-0.20)E+23 nuclei/cm2 in thick. G004500100022 The average loss of incident-beam photons due to G004500100023 absorption in the target was ~2%. G004500100024 DETECTOR (NAICR) 3 large-volume segmented NaI(Tl) to detect G004500100025 compton-scattered photons with an energy resolution G004500100026 of better than 2% (FWHM) at ~100 MeV.
