Publikováno v: Physics of Plasmas

Hot electrons created in laser plasma interaction at laser intensities 1−10 PW cm−2 in shock ignition scheme can deposit their energy in the shell of the target, augmenting the strength of the ignitor shock. Here, we present a model that describe

Publikováno v: Plasma Physics and Controlled Fusion

The shock ignition scheme is an alternative approach, which aims to achieve ignition of fusion reactions in two subsequent steps: first, the target is compressed at a low implosion velocity and second, a strong converging shock is launched during the
