- Abstract
- Problems appearing with detector calibration at neutron generators were emphasized and the alternative method of absolute calibration of diamond detectors using the 241Am+Be neutron source was realized. Measurement and numerical simulation of amplitude spectrum of diamond detector response under isotopic 241Am+Be neutron source radiation were carried out. The estimation of the detection efficiency of fast neutrons by diamond detector using amplitude spectrum region of (n,α) reaction on carbon for neutrons in energy range from 8.7 to 10.7 MeV was performed. Calculated effective volume of testing detector is equal to 80 % from physical size of diamond under its contacts. The advantages and disadvantages of usage of isotopic neutron sources for diamond fast neutron detectors calibration are showed.
