The energetic ions were produced at burnt-through foils with low-to-high atomic numbers (Al, Ag, Ta). The formation of the outflow plasma was investigated using the three-frame interferometry, the observed density distribution was complemented by numerical modeling of the plasma parameters based on the Arbitrary Lagrangian Eulerian code PALE. The found optimum conditions for the jet production were used in a design of alternate experimental configurations. The interaction of the directional plasma flows with secondary targets was studied via x–ray imaging, optical and high–resolution x–ray spectroscopy. The examples of jet applications for investigating the transition phenomena at surfaces of plasma-exposed solids are presented.
