Abstract
A spin tuned magnetron has a spinner the axially facing end of which lies in an inclined plane and an anode vane ring having an annular flange the end face of which lies in an inclined plane so that the amount of overlap of the flange and spinner varies as the spinner rotates. (In the FIG. 4A the spinner and the ring are shown spaced far apart; in practice they are spaced so that the planes coincide when parallel).
