Electron beam ionization based ionic wind device

Abstract

An electron beam ionization based ionic wind device includes a vacuum chamber, an electron source, an electron beam accelerating electrode, an electron beam exit window, and an ion accelerating electrode. The electron source is positioned inside the vacuum chamber and used to generate an electron beam. The electron beam accelerating electrode is positioned inside the vacuum chamber, on a chamber wall of the vacuum chamber, or outside the vacuum chamber, and used to accelerate the electron beam. The electron beam exit window is positioned on the chamber wall of the vacuum chamber. The electron beam is emitted to the outside of the vacuum chamber through the electron beam exit window and ionizes gas molecules or is attached to gas molecules outside the vacuum chamber to form ions. The ion accelerating electrode is positioned outside the vacuum chamber and used to accelerate the ions to generate ionic wind.
