The effects of initial load radius; on high photon energy nested wire arrays at the Z accelerator

Summary form only given, as follows. There have been numerous experiments in recent years studying K-shell X-ray sources using both gas puff and wire array loads. Most of this work has been limited to photon energies below 4 keV, however. At the Z facility, with a, peak current of 20 MA, higher photon energies can be studied. Previous work on high photon energy K-shell sources at Z has focused on the scaling of the radiated output with photon energy and comparison to established K-shell scaling theories. Experiments have also been performed to study the effects of initial load radius on the radiated output of >5 keV K-shell sources. In this paper, the results of experiments using nested stainless steel (6.7 keV) and copper (8.4 keV) wire arrays will be presented.
