摘要: The microwave plasma cathodes (MPC) dedicated to high‐current ion sources are characterized by long lifetime with reactive gases and a compact structure. An Ishikawa‐type MPC developed at GSI Darmstadt coupled the CHORDIS source is presented. electron current of extracted from dense generated under electron‐cyclotron‐resonance condition. axial magnetic field produced permanent magnets ferromagnetic components. 2.45 GHz power (some tens watts) introduced into chamber via coaxial line ended helical antenna. Experiments argon oxygen gas presented discussed.
