Abstract

The direct (fast) ignition of the compressed DT and DD fuels of ICF targets by the light ions of laser-produced plasma flows is proposed. Plasma flow, with necessary parameters, is generated as result of laser-produced thermal explosion of a thin separate foil, placed near ICF target. The foil thickness must be less than energy deposition length of the fast electrons inside the produced plasma. It ensures the volume explosion of such a target-generator along all of its thickness in the process of multiple fast electron crossings of the foil. In such a condition the light ions energy may be controlled at the optimal laser energy coupling in the target-generator. Direct ignition method by laser-produced plasma flow is more preferable in comparison with the method by laser-produced fast electrons beam on the reason that the complex procedure of a boring of ICF target plasma doesn't need.
