Abstract
A comprehensive set of 32 solid-state thermal neutron detectors, known as Silicon-LithiumFluoride (SiLiF), has been successfully developed and characterized. Key features for industrial application: The SiLiF detectors are suitable for the monitoring of nuclear materials and can be deployed around radioactive waste drums potentially containing small quantities of actinides, as well as around spent fuel casks during interim storage or transport. Appropriate polyethylene moderators can be employed to optimize the detector response to the expected neutron energy spectrum, as determined through Monte Carlo simulations. These detectors were extensively tested using an AmBe neutron source, and the results demonstrate highly uniform and reproducible performance.
