Abstract

The presence of an electron beam in a quasi-optical gyrotron cavity alters the structure of the fields from that of the empty cavity. A computer code has been written which calculates this alteration for either an electron beam or a thin dielectric tube placed in the cavity. Experiments measuring the quality factor of such a cavity were performed for the case of a dielectric tube and compared with the predictions of the code. Simulations of the case of an electron beam indicate that self-consistent effects are relatively small provided the device operates at or near the optimum detuning.
