Diamond is considered one of the most promising materials for neutron reaction studies and neutron fluence measurements. A newly built diamond detector and associated electronics were developed by the CIVIDEC Instrumentation for in-beam neutron measurements in harsh environmental conditions (high instantaneous neutron flux, high gamma-ray background, etc). Various tests were performed to determine the detector’s response to neutron environments including a measurement at NCSR “Demokritos” with monoenergetic neutron beams and a corresponding one at the newly built experimental area NEAR station at the n_TOF facility at CERN. The preliminary results of the tests for the development of this novel detection system will be presented and discussed.
