Progress in pulsed power technologies has enabled the use of z pinches for inertial confinement fusion (ICF). Z pinches can provide x-ray powers of 200 TW and x-ray energies approaching 2 MJ. Computational capabilities have advanced to the point that 2-D radiation magneto-hydrodynamics computer codes can be used as detailed design tools. Several ICF configurations have been proposed. The z-pinch driven hohlraum configuration (ZPDH) uses two separate z pinches to provide the radiation to drive an ICF capsule. The decoupling of the z-pinch from the target in the ZPHD permits physics issues such as radiation production, transport, symmetry, and capsule hydrodynamics to be treated separately. The penalty is the increased energy requirement. ZPDH experiments have demonstrated the potential for acceptable capsule symmetry and radiation transport. The dynamic hohlraum concept uses the z pinch itself as a radiation case around the capsule providing the potential for very high coupling efficiency but at the expense of complex z-pinch/target coupling physics.
