Attaining High Velocities for Impact Ignition by Winterberg

Attainability of high velocities for impact ignition (page pdf) by Winterberg To reach the flyer plate velocities in excess of 1000km/sec required for impact ignition, it is proposed to combine the ablation acceleration of a dense hydrogen jet by its isentropic compression in a convergent Prandtl-Meyer flow, magnetically insulated by the Nernst effect against the …

More from the Steve Chen Supercomputer Interview

The Chinese government supports university research and gives them money to pay for the use of the service [supercomputer grid]. That is better than to spend money on buying thousands of separate smaller systems and none of them can do significant work. China only has two supercomputer centers now. Steve Chen is recommending and apparently …
