E.A. Chandler;P. Egan;J. Stokes;R.D. Fulton;N. King;D. Morgan;A. Obst;H. Oona;D. Oro;D. Platts
Summary form only given. We have used the LANL PEGASUS Z-pinch facility to drive a thin cylindrically-convergent Al liner to /spl sim/3 km/s to launch /spl sim/30 GPa shocks in a 3-mm thick 10-mm-i.d. aluminum cylinder whose interior is filled with 1 atm Xe gas. The subsequent material motion of the metal and gas is diagnosed with both radial and axial flash X-rays and with optical framing cameras...Show More

D.M. Oro;R.D. Fulton;J. Stokes;J.A. Guzik;P.J. Adams;D. Morgan;D. Platts;A.W. Obst;M. Fell
Summary form only given. Experiments on the Pegasus II pulsed power facility at Los Alamos are being conducted to study the evolution and flow of strengthless materials as a result of being shocked. Of particular interest is vorticity and mixing that is induced in the materials by a shock-wave passing through a non-uniform boundary. The experiments provide an important benchmark for hydrodynamic c...Show More

Pulsed power driven cylindrical shock physics experiments are being performed at the PEGASUS facility at Los Alamos National Laboratory. A time dependent, axial X-ray imaging capability forms a subset of the measurements to quantify material behavior during shock propagation. 20 ns pulsed W target X-ray sources with about 10 mR at 1 m form the backlighter. Inorganic scintillators generate time dep...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

Year: 1997 | Conference Paper |
Many pulse power applications in use at the Pegasus facility at the Los Alamos National Laboratory require specialized imaging techniques. Due to the short event duration times, visible images are recorded by high-speed electronic framing cameras. Framing cameras provide the advantages of high speed movies of back light experiments. These high-speed framing cameras require bright illumination sour...Show More

When a shock wave interacts at the surface of a metal sample "ejected matter" (ejecta) can be emitted from the surface at velocities larger than the sample velocity. The mass, size, shape, and velocity of ejecta varies depending on the initial shock conditions and the target's material properties. In order to understand this phenomena, diagnostics have been developed and implemented at the Pegasus...Show More
