Abstract

A time-, position-, and energy-resolved soft x-ray (100-500 eV) diagnostic is being developed for PBFA II target experiments. The diagnostic provides measurements of hydrodynamic motion and thermal gradients in light-ion fusion targets. A slit-image of the x-ray source is imprinted onto thin sheets of organic scintillator to create a 1D image. The scintillator light is then proximity-coupled to a linear array of fiber-optics that transports the light to a streak camera operated without an intensifier. The streak camera output is recorded on a CCD camera. We are characterizing the spatial and temporal resolutions of the systems. Data is collected from as many as 90 individual fibers and corrected for variations in throughput and to roughly 5% standard deviation in their relative throughput. Spatial resolution of these systems at the source is approximately -.4 mm. Timing resolution is nominally 2 ns and is limited primarily by the scintillator response and dispersion in the 50-m-long fiber array. We describe the measurement techniques and the results of the characterization.
