Abstract
We present first results from a novel experimental platform which is able to
access physics relevant to topics including indirect-drive magnetised ICF;
laser energy deposition; various topics in atomic physics; and laboratory
astrophysics (for example the penetration of B-fields into HED plasmas). This
platform uses the X-Rays from a wire array Z-Pinch to irradiate a silicon
target, producing an outflow of ablated plasma. The ablated plasma expands into
ambient, dynamically significant B-fields (~5 T) which are supported by the
current flowing through the Z-Pinch. The outflows have a well-defined
(quasi-1D) morphology, enabling the study of fundamental processes typically
only available in more complex, integrated schemes. Experiments were fielded on
the MAGPIE pulsed-power generator (1.4 MA, 240 ns rise time). On this machine a
wire array Z-Pinch produces an X-Ray pulse carrying a total energy of ~15 kJ
over ~30 ns. This equates to an average brightness temperature of around 10 eV
on-target.
