Measurements and calculations of neutron detector efficiencies

Investigation of states in17F by the15N(3He,n)17F reaction

“…The low energy neutron bias was set at a pulse height equivalent to that produced by the 60 keV photopeak of 241Am. The absolute efficiency of the neutron detector was determined with the computer program DETEFF [12] and was checked with efficiencies determined from measurements of the 2H(d, n) 3He reaction using gas targets of known thicknesses and the known absolute differential cross sections [13]. Both neutron and ?-ray spectra were recorded and stored on magnetic tape enabling a check of the n-?…”

SCINFUL: A Monte Carlo based computer program to determine a scintillator full energy response to neutron detection for E/sub n/ between 0. 1 and 80 MeV: Program development and comparisons of program predictions with experimental data

“…The purpose of the computer program SCINFUL is to compute by Monte Carlo methods the complete response of a scintillator detector to incident neutrons. There are anumbev of existing computer programs [1][2][3][4][5][6][7][8][9][10][11][12] designed to predict, if not complete responses, at least the efficiencies of such detectors for a few selected thresholds, where efficiency is defined as the number of detected events (having pulse heights > threshold) per number of neutrons incident upon some surface of the detector. A well used, and copied, program is tie 20-year-old ORNL program 05S.…”
