Title: High-Spatial-Resolution Imaging of Low-Energy Neutrons with Microchannel Plates

Abstract

Nondestructive testing by neutron radiation yields information that complements other techniques that utilize penetrating radiation. However, the rapid and spatially resoled detection of neutron fields necessary to produce images is not well developed. Nominally, neutrons have weak interaction cross sections that limit spatially resolved determinations of flux density and energy spectrum. A few exceptional nuclides that are useful for thermal and subthermal neutron detection include {sup 3}He, {sup 6}Li, {sup 10}B, and {sup 148}Gd. Reactions involving these nuclides produce energetic charged particles that can be more readily detected; however, the implementation has not led to fast, efficient, spatially resolved detectors near the ability of other radiation detector schemes. Hence, NOVA Scientific (NOVA) has adapted the technology of microchannel plate (MCP) photomultipliers to develop a more effective neutron imaging detector system. This paper describes this work and results.
