Abstract
PURPOSE: To provide a bigger area of heat radiation, and enhance an efficiency in the magnetic field, by arranging a ferrite magnet inside the anode cylinder made from magnetic material.
CONSTITUTION: To the inner surface of an anode cylinder 31, constructed by magnetic material into a cylindrical shape, are secured a plurality of vanes 2 radially arranged in the surroundings of a cathode 1. In the both end faces of the anode cylinder 31, protrusively provided vacuum sealed substances 12 and 13 are secured by a step unit 6, supporting the cathode 1, and an antenna unit 7, including an output lead-out wire 14 and secured to the vane 2. To the bottom of the sealed substance 12, 13, is secured a pole piece 4, 5, for supplying a magnetic field to a working space A, and in the vacuum outside bottom of the sealed substance 12, 13, is placed a ferrite permanent magnet 8, 9. In this way, the overall magnetic circuit, with the anode ring included, is miniaturized, and a magnetic efficiency can be improved, and an area of heat radiation can be also widened.
