The Atlas facility, now under construction at Los Alamos National Laboratory (LANL), will provide a unique capability for performing high-energy-density experiments in support of weapon-physics and basic-research programs. Here, the authors describe how the primary element of Atlas is a 23-MJ capacitor bank, comprised of 96 separate Marx generators housed in 12 separate oil-filled tanks, surroundi...Show More
Atlas will be a 23 MJ capacitor bank capable of delivering greater than 30 MA to a liner target with a nominal 4 microsecond risetime. We describe here our ongoing diagnostic development efforts in this extreme Atlas environment. Included in this discussion are development efforts in X-ray radiography, shock physics diagnostics, and temperature and pressure diagnostics. X-ray radiography is the ke...Show More
Atlas is a pulsed-power facility being designed at Los Alamos National Laboratory to perform high-energy density experiments in support of Science-Based Stockpile Stewardship and basic research programs. Atlas will consist of 24 individual maintenance units, each consisting of 4 240-kV Marx units. Maintenance units are contained in large oil tanks arrayed in a circle about a central target chamber...Show More
Summary form only given. One experimental campaign planned for the pulse power facility, Atlas, will be devoted to the investigation of strongly-coupled plasma (SCP) effects on transport phenomena and equations-of-state in high-Z materials. Methods for forming strongly coupled plasmas using the pulsed-power facility, Atlas, are currently under investigation. For SCP experiments being planned, a me...Show More
Summary form only given. Atlas is a high current (/spl sim/30 MA peak, with a current risetime /spl sim/4.5 /spl mu/sec), high energy (E/sub stored/=24 MJ, E/sub load/=3-6 MJ), pulsed power facility which is being constructed at Los Alamos National Laboratory with a scheduled completion date in the year 2000. When operational, this facility will provide a platform for experiments in high pressure ...Show More

Atlas is a high energy pulsed power facility under development at Los Alamos National Laboratory to perform high energy-density experiments in support of the DoE's stockpile stewardship responsibility. Its design is optimized for materials properties and hydrodynamics experiments under extreme conditions. Atlas will be operational in late-1999 and is designed to provide 100 shots per year. The Atl...Show More
Atlas will be a high-energy (36 MJ stored), high-power (/spl sim/10 TW) pulsed power driver for high energy-density experiments, with an emphasis on hydrodynamics. Scheduled for completion in late 1999, Atlas is designed to produce currents in the 40-50 MA range with a quarter-cycle time of 4-5 /spl mu/s. It will drive implosions of heavy liners (typically 50 g) with implosion velocities exceeding...Show More
The Rayleigh-Taylor Mix (RTMIX) project will attempt to diagnose and understand the growth of a mixing layer at the interface between an imploding metal liner and a polystyrene foam core in a series of pulsed power experiments on the Pegasus capacitor bank. Understanding the effects of material strength will be an important part of the study. During the initial phase of the implosion, the liner/fo...Show More
