A Si-Pin Detector Used For Dpf Neutron Yield Measurement

In 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 analysed. 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.
