Show Abstract
This paper is aimed at the explanation of mechanisms responsible for plasma jet formation: the radiative cooling of ablative plasma and the influence of target irradiation geometry. The experiment was carried out with the Prague Asterix Laser System (PALS) iodine laser. A three-frame laser interferometer and an x-ray streak camera were used as two main diagnostic tools. These investigations have shown that the geometry of target irradiation is crucial, an annular target irradiation being necessary for plasma jet formation. Thus the role of radiative cooling in the plasma jet forming seems to be negligible.

Show Abstract
Introducing a striped electrode in a large area discharge allows us to transport microparticles in the discharge in a user defined way. A directed and continuous dust transport is established by modulating the voltage signals on all individual electrodes to cause a traveling plasma sheath distortion. Particles, trapped in the potential wells and thus following the distortions, are finally removed from the central discharge region. Transport efficiency and velocity can be controlled by changing amplitude and traveling velocity of the plasma distortions.
