摘要
用60Co标准源和HPGe探测器对狭缝式裂变中子探测系统(电流型)的γ灵敏度进行了实验探索研究,并计算了同样的235U-HPGe系统结构的理论能谱,实验能谱与理论能谱一致,进而得出235U-PIN系统的γ辐射灵敏度。
The sensitivity of slot-collimated PIN fission neutron detecting system （electrical current type） to γ-rays was studied by using an HPGe detector （counter type） and a ^60Co source. Gamma-ray energy spectrum from a ^235U-HPGe system of the same structure was simulated. The measured energy spectrum agreed well with the simulated spectrum. By replacing the HPGe with PIN, we obtained the γ sensitivity.
