AST Announces
Enhanced Neutron Detection Screens

Applied Scintillation Technologies (AST) Ltd has developed a new neutron detection screen which gives up to 20% improved efficiency of detection and improved signal to noise ratio. The screens provide good resolution and overcome the size, cost and handling difficulties of alternative 3He detectors.

AST neutron detection screens are formed from a blend of 6Li compounds and phosphors and make use of the reaction between 6Li and thermal neutrons to produce energetic tritons (tritium nuclei) which in turn interact with the phosphor to create light that can be detected by a photomultiplier tube or CCD imaging system.

The new screens feature increased 6Li loading per unit area, which gives up to 20% increase in neutron capture whilst maintaining minimal response to gamma rays that could interfere with the neutron signal. In addition, the screens exhibit improved signal-to-noise.

The new screens are available in large area formats (up to 1m x 1m) but can also be produced in novel shapes. This allows the screens to be designed to offer an increased area for neutron capture for individual applications.

The new screens are of great interest to the high-energy physics community with Oak Ridge National Labs, Rutherford Appleton Labs and JAEA all looking at utilizing this product in their new detector designs. Other neutron detection applications include studies of fuel flows in jet engines, authentication and restoration of paintings, crystallography and the identification of plastic explosives.
