Advanced study of ICF-energy direct conversion for LaserFusion Rocket with quasi-dipole field in the laser-plasmaexperiments and PIC–simulations

摘要

We had studied by the methods of numerical and laboratory simulations anrnimportant problem of direct inductive conversion of the ICF-plasma’ energy into electric one,rnunder conditions of promising space propulsions with magnetic nozzle. For such kind of LaserrnFusion Rocket, like a VISTA, with the strong and dipole-like magnetic field, a minimal 5%-rnlevel of conversion efficiency is required to supply a need power for laser system etc. As arnresult of calculations by 3D/PIC-code of KU a real opportunity to achieve this value wasrnconfirmed for the first time with taking into account a data of simulative experiments at KI-1rnfacility of ILP. A schemes and results of “VISTA-KI” experiments with Laser-Plasma cloudsrnis discussed to verify this opportunity under real conditions of flute-like plasma instability andrnthe geometry of plasma expansion (versus the main and pick-up coils) close to VISTA.
