• Summary form only given. On the 7-MA Saturn generator, we produced 4-ns duration, 75 TW X-ray power pulses using tungsten wire arrays. The radiated power increased as the wire number increased, as the velocity increased and/or as the wire size decreased. 2-D, 3-T radiation MHD calculations indicated that the wire size decrease could be represented by a decrease in the initial seeding of R-T instabilities. These calculations also showed that the increased collapse velocities result in higher electron temperatures. Initial experiments with 40-mm, 120 and 240 wire arrays on the 18-MA PBFAZ generator have produced 1.85 MJ, 160 TW of X-ray power in a 8.5 ns pulse. In this paper, we will present the scalings from Saturn to PBFAZ and results from and calculations of a radius scan that will optimize the output power by varying the implosion velocity (hence electron temperature and density) and the electrical coupling to the load.
