Abstract:
The stability of the neutron response function and the detection efficiency of a sCVD diamond detector in the temperature range up to 200 °C are demonstrated in this paper. A CIVIDEC neutron detector was simultaneously heated with an AmBe neutron source. This enabled the measurement of the spectrum of the deposited energy in the diamond sensor, i.e. the neutron response function of the detector and the detection rate, which in combination represents the neutron flux as a function of temperature. The measured temperature stability of the neutron response function of the detector and detection rate demonstrates the suitability of sCVD diamond detectors for harsh environments, such as encountered in geodetic applications and nuclear fusion research.
