A128100100016 The triple-coincidence requirement reduced neutron- A128100100017 induced background from 2H(d,n)3He as well as cosmic A128100100018 ray background. A 5 cm thick Pb shield was placed A128100100019 around the detector assembly, and a 2.5 cm thick, A128100100020 48 cm x 48 cm plastic scintillator was placed A128100100021 on top of the assembly, yielding a total cosmic-ray A128100100022 suppression of about 300 for E(gamma)=20-40 MeV.
