摘要：

PBFA Z is a new 60-TW/5-MJ electrical driver located at Sandia National Laboratories. We use PBFA Z to drive z pinches. The pulsed power design of PBFA Z(1) is based on conventional single-pulse Marx generator, water-line pulse-forming technology used on the earlier Saturn(2) and PBFA II3 accelerators. PBFA Z stores 11.4 MJ in its 36 Marx generators, couples 5 MJ in a 60-TW/105-ns pulse to the output water transmission lines, and delivers 3.0 MJ and 50 TW of electrical energy to the z-pinch load. Depending on the initial load inductance and the implosion time, we attain peak currents of 16-20 MA with a rise time of 105 ns. Current is fed to the z-pinch load through self magnetically-insulated transmission lines (MITLs). Peak electric fields in the MITLs exceed 2 MV/cm. The current from the four independent conical-disk MITLs is combined together in a double post-hole vacuum convolute with an efficiency greater than 95%. We achieved x-ray powers of 200 TW and x-ray energies of 1.9 MJ from tungsten wire-array z-pinch loads.
