GaAs and Higher Z PCDs for Flash X-ray Diagnostics

We will develop, demonstrate, and commercialize detectors, dose rate monitors, ratio monitors, and other diagnostics using GaAs and higher Z PCDs. In order to ensure the reliability and efficacy of the detectors, they will be subjected to a stringent testprotocal that will evaluate them agianst 8 performance requirements. In Phase II we will design and demonstrate spectrometers and other diagnostics that use the PCDs developed. As part of the demonstration we will use the diagnostics to characterize flashX-ray sources with endpoint energies up to 1.5 MeV. (1) GaAs PCD for the direct measurement of dose rate GaAs.(2) Commercial source for detectors and diagnostics using GaAs and other high Z PCDs for use for the characterization of flash X-ray sources withendpoint energies up to 1.5 MeV. The availability of these detectors will enable the design of spectrometers and other diagnostics with significantly improved spectral resolution.(3)The detector technology developed will also have significant non-DTRAapplications in areas such as positron emission tomography (PET), single photon emission computarized tomography (SPECT), nuclear spectroscopy, radionuclide identification, dosimetry, radiation monitoring, and non-destructive testing.
