Application of InP:Fe photoconductors as a fast and sensitive soft x-ray detector and bolometer

Recently the authors demonstrated that InP:Fe photoconductors are fast (FWHM ∼ 150 ps), sensitive (2.7 x 10-3 A/W), and flat response soft x-ray detectors using synchrotron radiation from the Stanford Synchrotron Radiation Laboratory. The authors have applied these to the measurement of the radiation emitted by a collapsing annular gas (argon) puff z-pinch plasma. The detector was used in two modes of operation: (1) a filtered soft x-ray detector as a pinch diagnostic and (2) a fast unfiltered bolometer to measure the total radiated power as a function of time. They will compare the performance of the photoconductors to other common fast x-ray detectors and bolometers
