Abstract
Simulations of fast electron transport in imploded
targets are presented. We found that beam filamentation in low density zones
can prevent 1-2 MeV electron propagation towards the high density core. To
mitigate this effect, we have considered electrons with mean kinetic
energies of 4-5 MeV. The large stopping length of these electrons is
partially balanced by collective stopping, resulting in a good coupling of
the beam with the imploded target.
