| Abstract: | The interaction of relativistic electrons produced by ultrafast lasers focussing them on strongly precompressed thermonuclearfuel is analytically modelled. Energy loss to target electrons is treated through binary collisions and Langmuir wave excitation. The overall penetration depth is determined by quasielastic and multiple scattering on target ions. It thus appears possible to ignite efficient hot spots in a target with density larger than 300 g/cc. |
