The impedance of the magnetron in different regions of the frequency spectrum

A description is given of a series of measurements on the impedance of the magnetron and its relation to the operating conditions in different regions of the frequency spectrum. The object of the experiments was to determine the direct properties of the valve alone, in order to understand and explain the mechanism, of operation of the magnetron. This has not been completely possible, and it appears that a full explanation is difficult unless existing theories of electron motion in the magnetron, especially under dynamic conditions, are much extended.
