Computer modelling new generation plasma optical devices (new results)

We present new results of computer modeling two new generation plasma optical devices based on the electrostatic plasma lens configuration that open up perspective possibility for high-tech effective applications. There describe development numerical model computer simulation results of a wide-aperture non-relativistic intense electron beam propagating through an axially symmetric plasma optical lens with a non -compensated positive space charge and the results of some theoretical calculations. The described also the original approach to use plasma accelerators with closed electron drift and open walls for generating effective lens with positive space charge
