Abstract : Reasonably powerful and efficient first harmonic oscillations have been obtained from this gyrotron at values of beam current, applied magnetic fields, and frequencies mostly consistent with the linear gyrotron theory. This implies that the predictions for cavity Q times threshold power from the theory are, at least approximately, correct for the first harmonic. On the other hand the second harmonic oscillations predicted by this theory were not observed for the cavity geometry. One must conclude that either the theory is not equally as reliable for second harmonic interactions, or that the Q values for the modes in the present cavity are much lower than those estimated in Table 1. Measurements of threshold power and of cavity Q will hopefully help clarify the issue and eventually lead to efficient second harmonic radiation from this gyrotron.
