Abstract :
We report recent experiments demonstrating that application of an azimuthally varying axial magnetic field to microwave magnetrons causes a dramatic decrease in the microwave noise and virtual elimination of sidebands. This magnetic perturbation technique also causes rapid-startup of magnetrons; we call this novel technique "magnetic priming.".
