of X-ray emission on the XP pulsed-power machine for radiography,
producing x-ray radiation with photon energies up to 4keV1 .The XP
machine produces 350kA, with a rise time of 60ns. The
goal of this study is optimizing the hybrid x-pinch for Ti, Mn, Ni, and
Cu to determine reliability of the sources produced. This optimization will involve varying the
electrode gap distance, and wire diameter, while observing the number
of hotspots formed and their intensity. The optimization will then be
continued on the COBRA pulsed-power machine at up to 1MA, accounting for the wire scaling factors between XP and COBRA. A second goal is to explore the possibility of producing two predictable x-ray sources with reliable timing for time-resolved radiography by suitable choice of electrode gap spacing, wire diameter and current rise time.
