The gyrotron is inherently a high power source and is susceptible to single- and multi-mode nonstationary behavior. This imposes severe limitations on the performance of the gyrotron. In a recent theoretical study [1] of the gyro-BWO, however, it was shown that the axial field profile contracts in the nonlinear regime. This, therefore, suggests the possibility of stationary(saturated) operation at a beam current as high as two orders of magnitude above the nonstationary threshold that was predicted by early theories. |
