Abstract

We present a new neutron detection technology capable of high efficiency detection of thermal and cold neutrons with high spatial resolution. It is based on neutron-sensitive microchannel plates (MCPs) converting incident neutrons to electrons, which are then amplified and detected by a variety of different position sensitive readouts. The detection efficiency of those detectors can exceed 50% for thermal neutrons, while the spatial resolution can be better than 20 pm FWHM. Another attractive feature is the capability to time-stamp each incoming neutron with -microsecond resolution, allowing energy/material resolved studies with pulsed neutron sources. The MCP-based neutron detectors can also be combined with novel MCP-based neuron optics, allowing high resolution angular selective neutron imaging.
