Laser-driven electrodynamic implosion of fast ions in a thin shell

Collision of laser-driven subrelativistic high-density ion flows provides a way to create extremely compressed conglomerates and study their properties. This paper presents theoretical the electrodynamic implosion ions inside hollow spherical or cylindrical shell irradiated by femtosecond petawatt laser pulses. We propose apply very effective mechanism for acceleration in self-consistent field with strong charge separation, based on oscillation laser-accelerated fast electrons this near thin shell. Fast are generated outer side under irradiation intense It is shown that ions, particular protons, may be accelerated at stage energies tens hundreds MeV when sub-micrometer pulses an intensity 1021–1023 W cm−2.
