  • Plasma sources
    Patent number: 8400063
    Abstract: This invention relates to a plasma source in the form of plasma generator (13) which utilizes an antenna (11) and an RF source (12). The generated plasma flows into a chamber (14) and ions are accelerated out of the chamber (14) by grid (15). A body 16 is located in the volume for creating local losses and thereby reducing local plasma density.
