| Popis: | A new approach has been proposed for monitoring D–T neutrons in the system using neutron activation of flowing water via the 16 O(n,p) 16 N reaction. The basic idea of the approach is to utilize the Cherenkov light, which is produced by energetic β-particles from 16 N in water, in the vicinity of a neutron source and then transmit the light by an optical fiber to the remote light sensor. Further feasibility studies require development of a water Cherenkov detector with an efficient light collection system that satisfies neutron monitoring requirements. Two different designs of the water Cherenkov detector with a fiber readout, as well as results of their irradiation tests are presented in the paper. Designs and the experimental setup are not yet optimized for best performance; obtained detector parameters demonstrate potential capabilities of the proposed approach. |
