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...
