✦ Synopsis

A compact device for monitoring of fast neutron fluxes is presented. The device is based on single crystal diamond obtained by the Chemical Vapor Deposition technique coupled to a uranium converter foil where neutron interaction results in emission of charged particles detected inside the diamond. Thermal and fast neutrons are detected using natural uranium containing both 235 U and 238 U. Biparametric (pulse height and time of flight) data collection was used at the ISIS pulsed neutron source to distinguish events from 235 U, 238 U and from carbon break-up reactions inside the diamond.
