とするイオン源。 An arc chamber with an opening on one side that can be evacuated and serves as an anode, a plasma electrode provided on the open side of the arc chamber to extract ions, and a plasma electrode inserted into the arc chamber from the lid plate of the arc chamber to generate thermoelectrons. A cathode filament for supplying current to the cathode filament, a plate-shaped lining provided along the inner wall of the arc chamber, a current introduction terminal provided through the cover plate for supplying current to the cathode filament, and a current introduction terminal located inside the arc chamber. An ion source comprising a filament mounting bracket for attaching a cathode filament to the ion source, and a lining covering the lid plate is located closer to the cathode filament than the filament mounting bracket.
