The authors are studying phase-locking of overmoded gyrotrons at moderate power levels (approx. 100 kW) in an 85-GHz two-cavity TE1,3 gyroklystron oscillator configuration. The key issues to be addressed by the experiment are: (1) self-oscillation of the input cavity, (2) isolation of the input and output cavities due to mode conversion at cavity tapers, (3) excitation of the proper mode in the input cavity, (4) drift length limitation due to beam spread, and (5) phase sensitivity to beam voltage and current. An experiment that self-consistently addresses all of these issues has been designed. In order to ensure that the two cavities have precisely the same resonant frequency, the output cavity has been made continuously tunable. A tunable gyrotron oscillator experiment has been assembled to examine the operation of the tunable output cavity without the added complications associated with the input cavity.
