Characterization of a gyrotron cavity at 10 GHz
Abstract
Experiments were conducted to characterize a gyrotron cavity designed to operate in the transverse electric (TE(sub 021)) mode at 10 GHz. Small holes were introduced into the cavity to couple in and detect the probing power. Evaluation of the loaded Q factor is based on bandwidth measurements whereas the standing-wave electric field profile is determined by using perturbation techniques. Good agreement between measured and predicted values of resonant frequencies and Q factors for several fundamental TE modes is found.
