  • Electron cyclotron resonance ion generator device
    Patent number: 9852873
    Abstract: An electron cyclotron resonance ion generator device includes a metal tube subjected to a first potential and pierced by a first cavity forming a plasma chamber intended to contain a plasma; a second cavity forming a waveguide configured to inject a high frequency wave into the plasma chamber, an extraction system including an upstream end connected to the plasma chamber and a downstream end configured to be connected to an ion transport line, the connecting flange being subjected to a second potential, a magnetic field generator, and a ceramic tube in contact with the metal tube, the ceramic tube surrounding the metal tube and at least a part of the extraction system.
    Type: Grant
