Chemical vapour deposited (sCVD) diamond detectors are currently under study in the nuclear community. Their fast response, their ability to withstand high irradiation fluxes and additionally the envisaged possibility to perform simple neutron spectrometry, make them good candidates for in-core measurement. The LRS has started a joint development of a full new detection system based on this material with the CIVIDEC company. One of the main purposes is to work on the discrimination of gammas, thermal and fast neutrons (based on pulse shape analysis) for demonstrating its possible use in a mixed field.
