Certain cause of hidden deterioration of magnetron efficiency

A technique for parameter checking of oscillatory system of a magnetron is proposed, enabling to determine the cause of appearing of internal defects in the production of oscillators. It is shown that the ways of indirect estimation of "destruction" of spectrum of spatial harmonics of a HF field of a slow-wave structure of anode of magnetron make it possible to minimize the risk of appearing of internal defects, which result from the defects of its oscillatory system.
