Název v původním jazyce

Laser-produced aluminum plasma expansion inside a plastic plasma envelope

Popis výsledku v původním jazyce

Experiments carried out at the Prague iodine laser facility provided information on distribution of electron temperature in the outflowing plasma jets and time and space characteristics of ion emission, both registered at bare and constrained-flow Al targets. Plastic targets with an Al cylindrical insert of 0.4 mm in diameter as well as a bare Al targets were used. The lateral pressure effect of the plastic plasma was strong enough to guarantee the effective Al plasma compression. The electron temperature measurements shown that the Al plasma compression is accompanied by the temperature increase. Measurements confirm the earlier numerical predictions. The constrained Al plasma jet is very narrow and its axial velocity is considerably larger than the velocity of freely expanding Al plasma. Consequently, the plastic plasma envelope also strongly accelerates the Al plasma in its axial motion.
