ABSTRACT:
The electrode is circular in configuration, with a central opening, so that it has inner and outer rims. The electrode structure comprises a plurality of spiral-shaped vanes of conducting material which are separated by relatively thin slit-like openings. The spiral vanes begin at an inner boundary which is close to the inner rim of the electrode and rotate approximately one-half turn to the outer rim of the electrode. A portion of the electron beam, which is typically produced from a cathode energized by a high voltage source, strikes the electrode near the central opening, and travels along the vanes of the electrode to ground, thereby establishing a plurality of spiral current paths in the electrode. These spiral currents create a magnetic field about the center of the anode in the region of the electron beam, focusing the remainder of electron beam through the opening in the electrode.
