Paper Abstract

The fusion gamma has an advantage to measure fusion reaction history in the deuterium-tritium (DT) fuel implosion experiments. A gas Cherenkov detector is available to measure DT fusion gamma in a high background environment. Simulation is carried out by Geant4 to evaluate the conversion efficiency and the time response of this Cherenkov detector. The background gamma rays are roughly estimated based on ENDF/B-VII.0 data, and the signal-to-noise (SNR) is evaluated based on the simulated energy response curve. The simulation result and the SNR analysis are helpful to construct the Cherenkov detector at Shenguang-III facility.
