Measurements in quasi-monoenergetic neutron beams at the EC-IRMM Van der Graaf accelerator for calibration of the UAB PADC based neutron dosimeter
چکیده انگلیسی
The UAB PADC based neutron dosimeter was designed to have similar dose responses for thermal and for fast neutrons. A set of calibrations with ISO neutron sources and the realistic SIGMA neutron field at IRSN Cadarache showed this behaviour. Nevertheless, a noticeable decrease of the response to epithermal neutrons is expected because of the small values of cross sections for neutrons at this energy range. The EC NUDAME program gave the opportunity to expose several units of our dosimeter to quasi-monoenergetic beams at the IRMM Van der Graaf accelerator for calibration purposes. The revision of the IRSN Cadarache values with an improved uncertainty treatment and the results of the calibration at IRMM Van der Graaf, in relation to the reference values of the neutron source term obtained using our Bonner sphere spectrometer, are presented in this work.
