This is a brief review of last results of ongoing research of the new generation plasma optic devices on base of wide aperture cylindrical electrostatic plasma lens, that open up novel possibility for effective practical applications in modern high-tech. The most attractive new applications are removing microparticles from vacuum arc plasma stream as well as focusing large-area intensive electron...
Pulsed electron beams with high (1÷100 J/cm2) energy density are used in various processes involved in structural and functional modification of surface properties of materials and products. One of the main problems of successful electron beam application is to develop reliable and efficient methods of transport and manipulation of electron beams with high energy density. The paper presents new experimental...
This paper presents research results on focusing and transport of an intense (up to 100 A) nonrelativistic (up to 20 kV) pulsed electron beam using a positive space charge plasma lens. The electron source is based on electron extraction from the plasma of a hollow-anode vacuum arc discharge. The arc is initiated by a dielectric surface flashover. The emission hole is covered with a fine mesh grid...
We describe a new approach for the creation of effective axially symmetric plasma tools for focusing and manipulating high-current negatively charged particle beams, negative ions, and electrons. This approach is based on the fundamental plasma-optical concept of magnetic and electrostatic insulation of electrons and nonmagnetized positive ions providing controlled uncompensated positive-space-charge...
