摘　　要：介绍了Si PIN中子探测器的结构和测量原理 ,分析了探测器对 14MeV中子的灵敏度 .利用该探测器测量了等离子焦点装置的D T脉冲中子产额 ,实验结果与SDIN5 0 0探测器测量结果在 5In this paper, the structure and performance of the Si-PIN detector system are introduced. The neutron sensitivity of the proton recoil Si-PIN detector to 14 MeV neutron is analyzed. Meanwhile, the direct irradiation sensitivity is simulated by MCNP-4B program. Using the Si-PIN detector, the pulsed neutron yield from DPF device has been measured. The results are in accordance with the SDIN500 detector within 5% uncertainty.
