ABSTRACT:
Plasma apparatus comprises a vacuum vessel, a device for creating an open-ended magnetic field containing a plasma, a plurality of electrostatic plugs disposed at the open-ended portions of the magnetic field. At least one of the electrostatic plugs comprises a limiter attached to the vacuum vessel, provided with an inner hollow portion and arranged so as to confine the plasma, an anode electrode disposed at the open-ended portion and provided with an inner hollow portion extending along a direction of the open-ended magnetic field, a cathode electrode disposed with space from the anode electrode on the side opposite to the limiter and coaxially with the anode electrode and the limiter, a control electrode passing through a through hole provided for the cathode electrode and extending into the hollow portion of the anode electrode so as to operate to control electrode density thereby to determine the space potential distribution, and electric power applying means so that potentials are applied to the anode electrode, the control electrode, the limiter, and the cathode electrode so as to be higher in the stated order.
