Non-classic efficient cavity pressure acceleration method applied to obtain very fast and dense macroparticles

Original language description

In the investigations a scheme called cavity pressure acceleration (CPA) was applied, which allows propelling plasma objects in arbitrary direction in relation to the laser beam incident on a target and more efficient use of laser pulse energy absorbed and definitely increasing pressurencausing acceleration of the foils. CPA eliminates the basic contradiction of the classic ablative acceleration process, in which this way of getting high microprojectile velocity simultaneously leads to mass loosing and density decreasing. Results obtained on PALS (Prague Asterix LasernSystem) show that the application of the CPA method allows for speed of the driven plasma objects to obtain values (average velocity 6x107 cm/s) comparable with top global results. Several other important results were also obtained e.g.: successful attempt to drive very thicknfoils (up to 500 micro m Al) to the speed of 1.0x107 cm/s, the result is not having its counterpart in the literature and indication of a simple and effective method to significantly increase the density of driven objects without significant reduction of speed through the use of targets withn"covered channel", which leads to a much higher energy density transmitted by the driven object, and the very high pressure generated by it, which is very important advantage in terms of possible use in impact fast ignition experiments
