The influence of electron oscillation on plasma transport through a magnetic duct

A magnetic duct is inserted between the cathodic are plasma source and the chamber to eliminate the macroparticles. In this paper, the plasma output o f the magnetic duct is determined as a function of the magnetic field and t he bias voltage under the Bilek biasing mode and entire duct biasing mode. The computer simulation and the experimental result indicate that the (E) o ver right arrow x (B) over right arrow drift results in an extra diffusion flux under the Bilek biasing mode. The test verifying the electron oscillat ion was conducted in the magnetic duct biased in the Bilek mode. The electr on behaviour under Bilek biasing mode is different from that under entire d uct biasing mode. The Bilek biasing mode has a lower plasma output than the entire duct biasing mode.
