Abstract
A controlled experiment was done to study the response as well as the detection efficiency of CR-39 (DOP) detectors to very high energy neutrons originating from 9 Be (α, xn ) reaction at E α approx. 50 MeV from the Variable Energy Cyclotron at Calcutta. A NE213 liquid scintillation neutron detector coupled to a photomultiplier having neutron-gamma pulse shape discrimination property was used to record the neutron flux as well as the spectrum. The CR-39 results obtained are compared with the NE213 monitor data. The sensitivity of CR-39 for neutron detection comes out to be 5 tracks cm -2 mrem -1 for the high energy neutrons used.
