ABSTRACT
X-ray pinhole images are formed on microchannel plate striplines to time-resolve Z-pinch emissions. Applications include a study of Z-pinch linearity necessary for x-ray lasers, the evolution of hot spots, and a study of Z-pinch heating mechanisms. In particular, multiple pinholes per strip with different filters allow the spatial and temporal variation of different temperature regions to be studied.

    A stripline gated microchannel plate framing camera is used as a detector in a crystal spectrometer. Typical 10 ns time gates are fast enough to record the evolution of both heating and expansion of Z pinches. By introducing spatially imaging cross slits, an x-ray spectrum from a Z pinch has...

    Large-scale-length axial nonuniformities in imploding z pinches have been measured with a time-resolved framing pinhole camera and a filtered x-ray diode. The nonuniform initial conditions of the annular gas column result in a nonsimultaneous stagnation along the pinch axis. By tailoring the...

    The spatial distribution of intense MeV pulsed proton beams over 100 cm² area is measured with two techniques. An array of carbon-activation samples gives fluences of 100-400 J/cm² with 1-2 cm resolution. Continuous distributions with 3-4 mm resolution are obtained by imaging...

    An experimental series was performed at a pulsed-power 2.2 MeV flash radiography machine to determine the lower limits of its mass sensitivity. This machine uses a rod-pinch diode with accelerating potential of 2.2 MeV and 50 ns pulse duration. Tungsten, aluminium, and titanium rod anodes were...
