IPC: H01J23/00
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To miniaturize a magnetron or heighten the output of the magnetron by improving the cooling efficiency. SOLUTION: Yokes 5, 6 constituting a magnetron are constituted of three plate-like poles in the surrounding of a core tube 1 and two of the three poles are set face to face and the remaining one is arranged as to be an apex of a triangle formed by those three poles.
