Scattering-absorbing method for the detection of 16.7 MeV high-energy pulse gamma
Based on theoretical calculation and Monte Carlo simulation, this paper proposes a new method for the diagno-sing of 16.7 MeV high-energy pulse gamma, named "scattering absorption method". The ratio of the sensitivity of high-energy gamma to that of the low-energy background gamma can reach 106 to 108 by this new method. The sensitivity of 16.7 McV high-energy gamma ranges from 10-21 to 10-16 C·cm2. It's better than the traditional method which is based on the magnetic analyzer and Chcrankov detector on some aspects.
