摘要：

Gallium arsenide resistive photoconductors are widely used for the characterisation of picosecond radiation pulses. They are used to measure both the intensity and the temporal shape of the pulse. We have investigated the influence of the physical and electrical properties of high resistivity GaAs crystals (LEG, VGF) supplied by various manufacturers on the detector response to fast visible and gamma-ray pulses. The detectors characteristics : response time and sensitivity, were tested both before and after pre-irradiation with fission neutron at integrated doses in the range 5 x 10(14) to 1 x 10(16) neutrons/cm(2). The original GaAs material properties were found to have a significant influence on the neutron preirradiated photoconductor response times and sensitivities for integrated doses up to 1 x 10(15) neutrons/cm(2).
