摘要
为了监测强流氘氚聚变中子发生器的中子产额,设计了一套反冲质子望远镜中子监测系统.该系统由准直器、真空腔室、质子探测器安装筒组成.设计中,使用中子输运设计与安全评价软件(SuperMC)优化了准直器,将反冲质子望远镜安装在与D^(+)束流入射反方向,与束线夹角11.5°、距离中子源靶点130 cm处,得到所述反冲质子望远镜系统探测效率为6.20×10^(-9).在强流氘氚聚变中子发生器上进行了初步准直及调试,获得了该系统运行参数及反冲质子谱等实验数据,结果表明该反冲质子望远镜适用于强流氘氚聚变中子源中子产额的监测.
A recoil proton telescope system was designed for high intensity D-T fusion neutron generator(HINEG)neutron flux monitor.This system mainly consists of a collimator,a vacum vessel,and two silicon detectors.The shading effects of this collimator were optimized by Super Multi-functional Calculation Program for Nuclear Design and Safety Evaluation(SuperMC).rradiation damage of the silicon detector and detectors'service life was improved from these optimized.Recoil proton telescope was installed at the position back to the D^(+)beam line where distance from the target to telescope system is 130 cm,and the angle between the recoil proton telescope and the beam line is 11.5°.The detection efficiency of the recoil proton telescope was 6.20×10^(-9).Experimental data such as the operating parameters of the system and the recoil proton spectrum were obtained after preliminary collimated and debugging,the results show that the recoil proton telescope is suitable for high intensity fast neutron yield monitoring.
