| 1 | Generation of Nonlinear Force Driven Blocks from Skin Layer Interaction of Petawatt-Picosecond Laser Pulses for ICF显示文摘The discovery of the essential difference of maximum ion energy for TW-ps laser plasma interaction compared with the 100 ns laser pulses led to the theory of a skin layer model where the control of prepulses suppressed the usual relativistic self-focusing.The subsequent generation of two nonlinear force driven blocks has been demonstrated experimentally and in extensive numerical studies where one block moves against the laser light and the other block into the irradiated target.These blocks of nearly solid state density DT plasma correspond to ion beam current densities exceeding 10^10 A/cm^2 where the ion velocity can be chosen up to highly relativistic values.Using the results of the expected ignition of DT fuel by light ion beams,a selfsustained fusion reaction front may be generated even into uncompressed solid DT fuel similar to the Nuckolls-Wood scheme where 10 kJ laser pulses produce 100 MJ fusion energy.This new and simplified scheme of laser-ICF needs and optimisation of the involved parameters. | HeinrichHora CangYu HeXiantu ZhangJie F.Osman J.Badziak F.P.Boody S.Gammino R.Hoepfl K.Jungwirth B.Kralikova J.Kraska L.Laska LiuHong G.H.Miley P.Parys PengHansheng M.Pfeifer K.Rohlena J.Skala Z.Skladanowski L.Torrisi J.Ullschmied J.Wolowski ZhangWeiyan | 2004 | Plasma Science and Technology2004，6，1： | 0 |
