A two-frame flash x-radiography (FXR) system has been developed for studying the implosion hydrodynamics of particle beam driven, inertial confinement fusion (ICF) targets. This system consists of two micropoint flash x-ray sources, two gated x-ray cameras, and a mechanical framework for aligning these components with respect to the target. The tungsten micropoint sources yield a bremsstrahlung spectrum with an end-point energy of 600 keV, an x-ray dose of 8 mrad at 61 cm, a spot size of approx.100 ..mu..m, and an exposure time of approx.3 ns. A geometric magnification of 4 x was employed in this radiographic arrangement, with an overall system resolving power of 4 line pairs/mm. This system has been used successfully to observe relativistic electron beam (REB) driven, ablative pusher target implosions.
