    Abstract

    Revised simulations of ALT-like devices are presented. The results from these simulations closely match those from experiments and demonstrate the capabilities of the devices as applied to ramp compression of metals to pressures of 20 Mbar by imploding liners driven by ~10 MG azimuthal magnetic fields (with currents up to 55 MA). These results can be applied to the design of experiments on isentropic compression of materials.
