Planar wire arrays are studied at 3–6 MA on the Saturn pulsed power generator as potential drivers of compact hohlraums for inertial confinement fusion studies. Comparison with zero‐dimensional modeling suggests that there is significant trailing mass. The modeled energy coupled from the generator cannot generally explain the energy in the main x‐ray pulse. Preliminary comparison at 1–6 MA indicates sub‐quadratic scaling of x‐ray power in a manner similar to compact cylindrical wire arrays. Time‐resolved pinhole images are used to study the implosion dynamics.
