Subnanosecond current mode detectors for prompt physical process diagnosis

Subnanosecond current mode detectors for prompt physical process diagnosis 1 first-author 1 1 1 1 1 1 1 Institute of Nuclear Physics and Chemistry, CAEP, Chengdu 610003 Institute of Nuclear Physics and Chemistry, CAEP, Chengdu 610003 For prompt physical diagnosis, several types of subnanosecond current mode detectors have been developed, including scintillator detectors with large linear output current, GaAs:Cr and InP:Fe photoconductor detectors(PCD), and X-ray diodes(XRD), etc. The characteristic of scintillation light of BaF 2 crystal doped with La and of plastic scintillator ST1422 with slow component quencher are described. As for the photoconductor detectors, the main performance of neutron damaged GaAs:Cr and InP:Fe were studied. In addition, the spectral response of an XRD with coaxial leading-out end was also studied. These detectors have been successfully applied to nuclear test diagnosis and ICF research.
