  5. 9. Collisional effects on electrostatic shock waves and heating in laser-generated plasmas

    Författare :Andréas Sundström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma physics; inverse Bremsstrahlung; warm dense matter; binary collisions; electrostatic shocks; laser-plasmas;

    Sammanfattning : Electrostatic shock waves are associated with an electrostatic field structure propagating at supersonic speed through laboratory or astrophysical plasmas. Shock ion acceleration schemes, based on the strong electrostatic field in the shock structure, show promising potential due to the narrow energy spread of accelerated ions – which can be applied in plasma diagnostics, the generation of warm dense matter or medical purposes.
