Sausage and Kink EMHD Instabilities and Fast Electron transport

In the fast ignition concept of laser fusion it is desirable that the hot electron beam generated at the critical layer by the ignitor laser pulse propagates an adequate distance and deposits its energy to the compressed target core in a sufficiently localized region for the creation of hot spot. The mechanisms responsible for energy deposition can be due to (i) the classical coulomb collision cross section and (ii) collective interaction of the beam plasma system. The present work demonstrates a possible electromagnetic turbulence aided collective mechanism of stopping of the energetic electron flow in plasma. (Author)
