“…It should be borne in mind that for an equilibrium thermonuclear combustion wave [ 1 ] the peak temperature exceeds the temperature for D-T plasma ignition (where only the radiation losses compete with o-particle heating). These temperatures are T m a x = 6.9 keV and Tjg n = 4.4 keV, respectively.…”

“…The present paper proposes the use of a thermonuclear combustion wave [ 1 ] to increase the effectiveness of a system with a straight imploding liner [2,3]. Such an arrangement typically involves a combination of methods of containing the cylindrical D-T plasma column: in the axial direction the plasma is contained gas-kinetically, held in by the ends, and in the radial direction the pressure of the longitudinal magnetic field exactly balances the plasma pressure.…”

The existence of a pair of oncoming quasi-stationary longitudinal thermonuclear combustion waves is demonstrated in a plasma column with cold, dense ends while undergoing uniform radial expansion. It is shown that if a suitable set of parameters is selected, an exponential expansion of a cylindrical column is possible, during which the temperature, density and longitudinal velocity distributions remain unchanged with time and in which a continuous inflow of thermonuclear fuel is produced by convection driven by the combustion waves near the ends of the plasma column. A numerical procedure is used to find a self-consistent distribution of fusion power in the plasma with non-local thermalization of a-particles. -The usefulness of these thermonuclear combustion waves for increasing the effectiveness of an imploding liner system is discussed.

“…Equation-of-state data are determined from the Sesame Library (Bennet et al 1978;Lyon & Johnson 1992), and elastic properties of materials are based on the Steinberg models (Steinberg 1996). The program simulates shock hydrodynamics in planar, cylindrical, or spherical systems.…”

We describe the mathematical basis and organization of Crunch, a ID shock-hydrodynamics code to analyze pulsed-power experiments at Los Alamos National Laboratory. The program uses finite-element methods that preserve stability during material collisions and shock convergence on axis. It handles coupled calculations of nonlinear magnetic diffusion to simulate imploding liners. These calculations may be driven by multiple current waveforms or a selfconsistent current variation derived from a pulsed-power generator model. Crunch incorporates elastic material contributions and calculates element break and melt points. The primary goal in program development was effective use by experimentalists. Crunch is controlled by a streamlined script language and runs on standard personal computers. An interactive graphical postprocessor expedites analysis of results. To support the program we have assembled data resources in machine-independent format including Sesame equation-of-state tables, a material strength library and a library of temperature-dependent conductivities.
