Jupiter is a Sandia initiative to develop the next generation of fast Z-pinch drivers for applications to high energy density physics, inertial confinement fusion, and radiation effects simulation. Jupiter will also provide unique capabilities for science research in a broad spectrum of areas involving ultra high magnetic fields, hot/dense plasmas, x-ray physics, intense neutron sources, etc. The program is based on the premise that a single facility using magnetically driven implosions can meet the needs in these multiple program areas. Jupiter requires a 450-500 TW, 8-10 MV, {approx} 100 ns pulsed power generator to impart - 15 MJ kinetic energy to an imploding plasma load. The baseline concept uses a highly modular, robust architecture with demonstrated performance reliability. The design also has the flexibility to drive longer implosion times. This paper describes the Jupiter accelerator concept, and the research underway to establish the technological readiness to proceed with construction of the facility.

Intense beams of light ions are being developed at Sandia National Laboratories as a promising driver option for Inertial Confinement Fusion (ICF) implosions. The Particle Beam Fusion Accelerator II (PBFA II) will provide the physics basis for light-ion-beam driven ICF targets. Recent progress made in ion beam generation focusing on PBFA II has led to a record 5.4 TW/cm{sup 2} peak focal intensity with {gt}80 kJ proton energy delivered to a 6-mm diameter sphere. The driver-development program on PBFA II is reviewed. A design concept for a light ion beam driver for the Laboratory Microfusion Facility is also presented. 34 refs., 9 figs., 1 tab.
