Abstract :
Summary form only given, as follows. We have developed a near-axis time-resolved X-ray imaging capability to make measurements of the emission profile for foam targets on the Z accelerator. By slit-imaging spectrally filtered X-ray emission from the Z-pinch target to an array of scintillator coupled fiber-optics, we obtain an emission profile as a function of time sampling every 260 /spl mu/m viewing 4/spl deg/ from the z axis. The plasma run in and re-expansion are observed. Implosion velocities, and compressed sizes for annular and foam targets have been measured. We describe the diagnostics, results from the instrument and instrument characterization.
