    摘要: A method and apparatus for forming plasma sheets of preselected planar curvature, which can be used as mirrors for X-Band microwaves and above. A plasma is created using a shaped cathode. Confining magnetic fields maintains the plasma in the shape of the cathode. Additional magnetic fields can provide additional curvature to the plasma sheet.

    摘要: A method of and apparatus for controlling the potential of a plasma including a metal-walled chamber and a conductive coil which carries a radio-frequency current and is wrapped around the metal-walled chamber to produce a plasma within the chamber. A filament made of refractory metal has two ends, and a central portion formed in the shape of a probe. The central portion of the filament extends into the interior of the chamber and the two ends of the filament pass through a wall of the chamber to the exterior of the chamber. A heating power supply is connected to the two ends to the filament and to the chamber wall for heating the filament to a predetermined temperature above that of the plasma. The heated filament produces thermionic emissions from the filament to the plasma in order to control the plasma potential and eliminate unipolar arcing at the chamber wall.

    摘要: A method and apparatus for treating a work surface, wherein there is provided a chamber having a longitudinal axis and longitudinally extending electrically conductive sidewalls, at least one sidewall having at least one longitudinally extending gap that interrupts a current path through the sidewalls transverse to the longitudinal axis, and wherein the chamber is sealed to allow pressure inside the chamber to be controlled. Also provided is an axially-extending array of current-carrying conductors which at least partially encircle the chamber, are transverse to the longitudinal axis, and establish a magnetic field parallel to the longitudinal axis of the chamber, and a power supply connected to the conductor array and adapted to provide high-frequency current in the conductors to magnetically induce ionization of the gaseous material in the chamber and form a plasma sheath that surrounds and extends along the longitudinal axis and conforms to the sidewalls of the chamber, and wherein the work surface is exposed to the plasma sheath and extends in the direction of the longitudinal axis.
