The paper presents new generation plasma optical devices based on the electrostatic plasma lens configuration that opens a novel attractive possibility for effective high-tech practical applications. Original approaches to use of plasma accelerators with closed electron drift and open walls for the creation of a cost- -effective low-maintenance plasma lens with positive space charge and possible application for low-cost, low-energy rocket engine are described. The preliminary experimental, theoretical and simulation results are presented. It is noted that the presented plasma devices are attractive for many different applications in the state-of-the-art vacuum-plasma processing.

Experimental investigations were performed to evaluate the focusing properties of the plasma focus for high-energy intense ion beams manipulating. Magnetic probes and optical spectroscopy were used for temporal and spatial plasma geometry investigations. Ion beam portrait was determined at the luminescence screen. In the experiments performed, the focusing coefficient was obtained as the ten times beam compression at the 30 cm length. By variations of the gas volume input, gun voltage, time delay, magnetic field value etc. the dependence of focused ion beam diameter upon various parameters of the plasma focus lens has been investigated. It was revealed that the main focusing effect was caused by the azimuthal magnetic field of the currents carried by the plasma.
