Isentropic compression experiments on the Sandia Z accelerator

Z-pinch Driven Isentropic Compression for Inertial Fusion

The achievement of high gain with inertial fusion requires the compression of hydrogen isotopes to high density and temperatures. High densities can be achieved most efficiently by isentropic compression. This requires relatively slow pressure pulses on the order of 10-20 nanoseconds; however, the pressure profile must have the appropriate time history [J. Nuckolls et. al. Nature, 239, 139, 197...

Magnetically driven hyper-velocity launch capability at the Sandia Z accelerator

The intense magnetic field generated by the Z accelerator at Sandia National Laboratories is used as a pressure source for material science studies. A current of ∼20 MA can be delivered to the loads used in experiments on a time scale of ∼100e600 ns. Magnetic fields (pressures) exceeding 1200 T (600 GPa) have been produced in planar configurations. In one application we have developed, the magn...

Shock compression and isentropic release of rhyolite

Shock compression and isentropic release of granite

S U M M A R Y New equation of state data for a weathered granite shocked to about 125 GPa are reported and combined with the Westerly granite data of McQueen, Marsh & Fritz (1967). The shock velocity (Us)-particle velocity (Up) relations can be fitted with two linear regressions: Us = 4.40 + 0.6Up for a range of Up up to about 2 km s-' and Us = 2.66 + 1.49Up for a range of about 2 to 5 km s-'. ...

High Gradient Experiments on NLCTA Accelerator Structures

This paper presents new results of high-gradient studies performed on a 1.8 m traveling-wave accelerator section with detuned high-order deflecting modes. This .. structure was designed initially for studies of detuned structures and will be installed in the Next Linear Collider Test Accelerator (NLCTA). The paper describes the test set-up in the Accelerator Structure Test Area (ASTA) including...
