Abstract

PURPOSE:To prevent the effectiveness of a magnetron from being lowered even if the cathode voltage decreases, by properly presetting the radius measured from the center line of a cathode to the inner end face of an anode blade piece and the radius of the cathode. CONSTITUTION:An anode 2 is arranged around a cathode 1. This anode 2 radially fixes 12 rectangular anode blade pieces 4, 4... on the inner surface of an anode cylindrical body 3 at equal intervals. The cathode 1 is enclosed by the inner end faces of the respective anode blade pieces 4, 4... at specified gap size (g) and the space of these gap size (g) is used as actuating space (m). A magnetic field is applied to the actuating space (m) by a magnet. The radius Ra measured from the center of the cathode 1 to the inner end face of the anode blade piece 4 is present to 4.1-4.5mm. and the radius Rc of the cathode 1 to 2-2.34mm.. The anode voltage operates at 2.5KV.
