Název v původním jazyce

Direct spectroscopic observation of ion deceleration accompanying laser plasma?wall interaction

Popis výsledku v původním jazyce

Interactions of plasma jets with solid surfaces are studied in context with development of future fusion devices. In experiments carried out on the iodine laser system PALS, the energetic ions were produced at double-foil Al/Mg targets. The plasma jets from the laser-exploded Al foil streamed towards the secondary Mg target preheated by the action of the high-energy photons, particle and laser beams. The forward-accelerated Al ions collided with the counter-propagating matter ejected from the wall. Theenvironmental conditions in near-wall plasmas were analyzed with the high-resolution x-ray spectroscopy and temporally-resolved x-ray imaging. The deceleration of the incident Al ions was quantitatively characterized via Doppler shifts of the J-satellitefrom the Al Ly_alpha spectral group. The interaction scenario was modelled using the 2D arbitrary Lagrangian Eulerian hydrocode PALE and the multifluid code MULTIF.
