Generation of an Electron Beam by a Forevacuum Plasma Source with a Single Emission Channel in the Presence of Magnetic Field

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Consideration has been given to the effects of a longitudinal magnetic field in the discharge-emission system of a forevacuum plasma electron source on the conditions of generating a focused electron beam with high specific power. It has been shown that the creation of a magnetic field with an induction of up to 0.4 mT ensures the possibility of expanding the emission channel, and, accordingly, increasing the current and current density of the electron beam while retaining the electric strength of the accelerating gap. As a result, the power density of the electron beam of the forevacuum plasma electron source has been raised to the value q = 1.5·106 W/cm2.
