| Zusammenfassung | Radiation detectors made from artificial chemical vapor deposition (CVD) single crystal diamond have shown great potential for neutron spectrometry. The detectors are small, typically about (5 × 5 × 0.5) mm³, they are not very sensitive to gamma radiation, and they have good radiation hardness properties. They are, therefore, very promising candidates for applications where high resolution neutron spectrometry in very high neutron fluxes is required, such as in fusion research. A measurement with a single crystal CVD diamond detector results in a pulse height spectrum which contains information about the energy spectrum of the incident neutrons. Unfolding methods can be used to extract this information, but this requires a response matrix. Current particle transport codes, while able to provide important information, are of limited use because they cannot simulate neutron responses of CVD diamond detectors that are of high enough quality to be used for unfolding. Consequently, we have determined the neutron response matrix from measurements. |
