An Efficient Method for Generating and Extracting an Electron Beam into the Atmosphere in a Wide-Aperture Accelerator Based on Ion–Electron Emission

A new method is presented for increasing the coefficient of electron beam extraction into the atmosphere for accelerators with a non-self-sustained high-voltage glow discharge, which is characterized by high-frequency (tens of kilohertz) generation of an auxiliary discharge. An increase in the efficiency of beam extraction into the atmosphere is achieved by using a pulsed auxiliary glow discharge of the orbitron type, also called wire discharge, and by controlling the pulse duty factor of this discharge while stabilizing the average value of its current. Using the example of the accelerator under study, the possibility of increasing the output coefficient by 0.3 relative to the mode with direct current is shown.
