DirectRadiation Response of CdZnTe Detector to 14 MeV Pulsed Neutron Beam

CdZnTe (CZT) crystal is one of the most attractive materials used for the new type radiation detector due to its excellent material properties. The directradiation response of CZT detector to 14 MeV neutron was calculated by MonteCarlo code MCNP. The measurement of the CZT detector to 14 MeV neutron was performed on ING103 pulsed neutron generator. The results indicate that the theoretical value accords with the experimental result. When coverage factor is 2, the expand uncertainty is less than 14%. With the sensitivity of 1.28×10-16 C·cm2 to 14 MeV neutron, the CZT detector can be applied to the highintensity pulsed neutron measurement.
