An x-ray-driven high-mach-number jet experiment has recently begun on the Z accelerator. The 130-140 eV drive of a z-pinch-driven hohlraum ablates a cylindrical Al pin (300-micron-length, 600-micron-diameter) that is embedded half way into a 150-micron-thick Au washer. A convergent shock/mach cone is formed on axis, and the dense Al plasma propagates into a 250 mg/cc RF foam, on the opposite side, and a jet is formed. The jet evolution is imaged by a 6.151 keV curved-crystal imaging system with 10-11 micron spatial resolution. This allows the bow shock, Kelvin-Helmholtz roll-up, and other jet features to be studied in detail and then compared with various radiation hydrodynamics codes. In addition to code validation, such data is also of interest to the astrophysical community, particularly in the area of supernovae. Preliminary Z jet data will be presented.
