Název v původním jazyce

Generation of fast electrons in the external corona of laser plasma by the Raman scattering

Popis výsledku v původním jazyce

In the external part of the corona the laser plasma is only weakly collisional and the evolution of the electron distribution function is far from a Maxwellian one. The predominant mechanism causing these deviations is the particle trapping in electrostatic waves. The typical example producing these waves is the Raman scattering. The scattered Raman wave may grow strong enough to undergo a secondary scattering, which leads to a Raman cascade. The oscillating electrons have their own dynamics separate from that of the bulk thermal electrons, which gives rise to additional wave modes. One of them is the trapped particle instability, which broadens the electrostatic spectrum and leads to an intermittency. The electron phase space is hardly accessible to adirect measurement, so it makes sense to resort to a numerical modelling. This is effected by a solution of the Vlasov equation simultaneously with the Maxwell equations in a 1D periodic slab model by a transform method.
