Observation of Gamma Rays from Water Activated by D-T Fusion Neutrons

In this paper, the activation of light water was discussed focusing on 6.13 MeV gamma-rays from 16N. observation of emitted gammarays were carried out using an optimized setup that consists of a closed water loop including a D-T neutron generator, a spiral water pipe in the irradiation region and a shielding measurement area with a gamma-ray detecting system. The gamma-rays detecting system incorporate large volume BGO detector (φ 12.5 x 5 cm). The obtained gamma-ray spectra are given for different water rates and corresponding to different irradiation and decay times. These spectra confirm that the decay gamma-rays from 16N appearing in activated water were really observed by the proposed setup.
