Abstract

Because neutrons are uncharged, their detection usually involves organic scintillators that use nuclear reactions on hydrogen and carbon to produce charged particles. The energy deposited by these particles in the scintillator results in detectable light production. This paper uses results reported in recent papers to describe the operation of neutron detectors at energies below 200 MeV. 4 refs., 8 figs.

Detecting sub-MeV neutrons in solid plastic scintillator with gamma-ray discrimination

Conference Kovash, M A ; Daub, B ; French, J ; ...

We report on recent efforts to design a solid plastic scintillation hodoscope to measure neutron production cross sections at low energies. Our program includes not only the development of the detector itself, but also a set of auxiliary measurements which will help characterize its low-energy response. A novel scintillation counter has been developed to detect sub-MeV neutrons while rejecting gamma-ray backgrounds with good efficiency. The detector uses multiple layers of thin solid scintillator, with optical isolation between the adjacent layers. Incident low-energy neutrons produce ionizing recoil particles which remain within just one of the scintillator layers, while background gamma raysmore »« less

High-Resolution Cross-Section Measurements for Production of the 0.478-MeV Gamma Ray from the {sup 9}Be(n,x{gamma}){sup 7}Li Reaction for Neutron Energies Between 12 and 200 MeV with Insight into the {sup 10}Be Level Scheme

Journal Article Nelson, R O ; Michaudon, A - Nuclear Science and Engineering

Because of the low-energy threshold and relatively large cross section of the {sup 9}Be(n,2n) reaction, beryllium is a very attractive neutron multiplier for some fast-neutron systems, such as those used in the production of fusion energy. But, tritium is also produced when beryllium is irradiated with 14-MeV neutrons emitted from the fusion of deuterium and tritium ions. Among the two exit channels of the {sup 9}Be(n,t){sup 7}Li reaction of {approx}14-MeV incident-neutron energy, the {sup 9}Be(n,t{sub 1}{gamma}){sup 7}Li channel also emits a 0.478-MeV gamma ray. The purpose of the present study is to measure the cross section for the {sup 9}Be(n,t{submore »« less
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

Technical Report Dickens, J K

This document provides a discussion of the development of the FORTRAN Monte Carlo program SCINFUL (for scintillator full response), a program designed to provide a calculated full response anticipated for either an NE-213 (liquid) scintillator or an NE-110 (solid) scintillator. The program may also be used to compute angle-integrated spectra of charged particles (p, d, t, /sup 3/He, and ..cap alpha..) following neutron interactions with /sup 12/C. Extensive comparisons with a variety of experimental data are given. There is generally overall good agreement (<10% differences) of results from SCINFUL calculations with measured detector responses, i.e., N(E/sub r/) vs E/sub r/more »« less

Measurement of the scintillation and ionization response of liquid xenon at MeV energies in the EXO-200 experiment

Journal Article Anton, G. ; Badhrees, I. ; Barbeau, P. S. ; ... - Physical Review C

In this work, liquid xenon (LXe) is employed in a number of current and future detectors for rare event searches. We use the EXO-200 experimental data to measure the absolute scintillation and ionization yields generated by γ interactions from ²²⁸Th (2615 keV), ²²⁶Ra (1764 keV), and ⁶⁰Co (1332 keV and 1173 keV) calibration sources, over a range of electric fields. The W value that defines the recombination-independent energy scale is measured to be 11.5±0.5 (syst.) ±0.1 (stat.) eV. These data are also used to measure the recombination fluctuations in the number of electrons and photons produced by the calibration sourcesmore »« less

Neutron decay from the isobaric analog state in {sup 120}Sb populated in {sup 120}Sn({sup 3}He,{ital t}){sup 120}Sb at {ital E}({sup 3}He) = 200 MeV, {theta} = 0{degree}

Journal Article Roberts, D A ; Ashktorab, K ; Becchetti, F D ; ... - Physical Review, C

The {sup 120}Sn({sup 3}He,{ital t}){sup 120}Sb charge-exchange reaction has been investigated at {ital E}({sup 3}He) = 200 MeV and {theta}{approx}0{degree} to study neutron decay from the isobaric analog state at {ital E}{sub {ital x}}=10.20 MeV in {sup 120}Sb. The low-energy neutrons (average energy {similar_to}0.85 MeV) were detected in coincidence with tritons observed in the focal plane of a high-resolution magnet spectrometer. Four small deuterated NE230 scintillation detectors were mounted at distances of 9.5 cm from the target resulting in an overall neutron detection efficiency including solid angle of {gt}1%. This efficiency was obtained by combining the measured dependence on neutronmore »« less
