Abstract
Summary form only given. We have developed conceptual designs of two next-generation petawatt-class pulsed-power accelerators. The designs are based on the architecture described in Ref. [1]. The prime power source of both designs is a system of lineartransformer drivers (LTDs) [2,3]. Both designs use six water-insulated radial-transmission-line impedance transformers [1,4,5] to transport the power generated by the LTDs to a six-level vacuum-insulator stack. The stack is connected to six radial magnetically insulated transmission lines (MITLs); the MITLs are joined in parallel at small radius by a triple-post-hole vacuum convolute [6–9]. The convolute delivers the combined power of the six MITLs to a single short MITL that transmits the power to the load. The first accelerator will generate a peak electrical power of 300 TW, and deliver an effective peak current of 50 MA to a z pinch that implodes in 130 ns. This accelerator is 35 m in diameter, and will fit within the existing Z-accelerator building. The second, which is 52 m in diameter, will generate 800 TW, and deliver an effective peak current of 66 MA to a pinch that implodes in 120 ns. Both accelerators will allow high-energy-density physics experiments to be conducted over heretofore inaccessible parameter regimes.
