Optimization of Ti, Mn, Ni, and Cu Hybrid x-pinch X-ray emission in the 4-8keV photon energy range

The Hybrid X-Pinch has been shown to be an excellent point source

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.
