Název v původním jazyce

Laser-induced cavity pressure acceleration - a novel highly efficient scheme of acceleration of dense matter

Popis výsledku v původním jazyce

A novel efficient scheme of acceleration of dense matter is proposed and examined. In this scheme, a projectile placed in a cavity is irradiated by a laser beam introduced into the cavity through a hole and accelerated along the guiding channel by the thermal pressure generated in the cavity by the laser-produced plasma or by the photon pressure of the ultra-intense laser radiation trapped in the cavity. Using 1.315 mum or 0.438 mum, 0.3-ns laser pulse of energy up to 200 J and a thin target (CH, CD2) placed in the cavity it was shown that the forward accelerated dense plasma projectile produced from the target can be effectively guided and collimated in the 2 mm cylindrical or conical guiding channel and the energetic efficiency of acceleration in this scheme is an order of magnitude higher than in the case of conventional ablative acceleration.
