Neutron Detectors Using Slow Scan CCDs

Abstract

The readout of neutron scintillators via CCD cameras has proved to be an efficient and cost effective means of position sensitive neutron detection. Slow-scan CCDs work as integrating detectors, offering high count rate capability and high linearity, whereas intensified CCDs allow the analysis of single neutron events, thus providing good background rejection at lower count rates. This paper describes the workings of a slow-scan CCD camera for neutron detection and reports about properties of various types of scintillators, fiber optic devices, lenses and CCDs that are used for these detectors, and their influence on the detective quantum efficiency.
