Abstract :
Summary form only given, as follows. A series of Li beam ion hohlraum experiments are currently being conducted at the Particle Beam Fusion Accelerator II (PBFA II). Two scintillator based diagnostics coupled to fiber optics and recorded on streak cameras are being fielded on these target beam experiments. The purpose of the diagnostics was to measure X-ray flux. One uses a slit aperture to create a 1-D image of the X-ray source that is imprinted on a fiber optic-faceplate coated with (2 /spl mu/m thick) organic scintillator. Multiple arrays and filters are used to obtain 6-spatially resolved energy bands. The coated fiber optic faceplate is then proximity coupled to a linear array of fiber-optics that transports the light to a streak camera. The streak camera output is recorded on a charged-coupled-device (CCD) camera. The other diagnostic does not acquire an image but integrates the total X-ray flux to give a time-resolved broadband spectrum. We describe the diagnostics and the results of the diagnostic characterization in this paper.
