Mitigation of electromagnetic instabilities in fast ignition scenario

  • CLAUDE DEUTSCH (a1), ANTOINE BRET (a1) and PATRICE FROMY (a2)

Abstract

We address the issues of collective stopping for intense relativistic electron beams (REB) used to selectively ignite precompressed deuterium + tritium (DT) fuels. We investigate the subtle interplay of electron collisions in target as well as in beam plasmas with quasi-linear electromagnetic growth rates. Intrabeam scattering is found effective in taming those instabilities, in particular for high transverse temperatures.
