Neutron efficiency is determined by the ZnS:6LiF mass ratio and by the thickness of the screens. Typically, a higher thickness and a lower ZnS:6LiF ratio will provide a greater capture efficiency but a lower light output. This however will depend on incoming neutron flux and on the detector setup. The detection of thermal neutrons is based on the nuclear reaction
6Li + n → 3H + α + 4.78 MeV
Our specialist neutron detectors screens offer excellent neutron/gamma discrimination for low false detection rates. Manufactured in sheet form, which can be tiled to produce large area detectors, our neutron detectors are primarily used in Radiation Portal Monitors (RPM’s) to detect radiation within a container or vehicle.
Scintacor neutron scintillator screens couple well to light guides. With emission being efficiently collected from both surfaces, exceeding most customers’ requirements. The screens can be supplied as self-supporting sheets as well as mounted to a variety of substrates. The screens can be supplied to custom sizes or moulded into novel constructs.
Neutron screens are available in three formulations:
ND is a blue emitting screen with unique low sensitivity to background gamma.
NDg is green emitting which is ideal for CCD imaging.
NDFast has been specifically designed for high rate applications.
