Methodology Investigation of Neutron Device Monitors

Abstract

Various diodes have been investigated as monitors for 1 MeV equivalent neutrons. One particular diode, the DN-156, has proved suitable. It is not sensitive to thermal neutrons or gamma rays. Production uniformity is sufficiently good that batch calibration is suitable, and individual device calibration is not necessary. The device is not temperature stable, so precautions must be taken to obtain correct results. The DN-156 has been used to calibrate a test reactor neutron field to 9 percent, traceable to a national standard.
