The HDZP-II experiment uses a 2 MV, 1.9 {Omega}, 1.2 MA, 100 ns risetime pulsed-power driver. Preliminary experiments have been performed at 600--800 kA (half the bank energy). Preliminary results show the plasma heating to several kilovolts (although a non-Maxwellian distribution is likely) while maintaining an overall straight and reasonably uniform axial configuration. However, interferograms and x-ray pinhole photographs show the column expanding rapidly with considerable small-scale structure, presumably due to m=0 activity. The neutron yield (typically 5 {times} 10{sup 9}) is consistent with thermonuclear reactions at the reduced density although detailed study of the neutron characteristics has not been performed. Preliminary isotropy measurements do not show significant neutron anisotropy. 10 refs.
