Abstract : A frequency-selective stabilization system for a gyrotron traveling wave tube amplifier using a dielectrically loaded lossy auxiliary waveguide coupled to the interaction waveguide of the gyrotron traveling wave tube. The auxiliary waveguide has its cutoff frequency in the range of that of the interaction waveguide where instability is likely to occur, but has a significantly different dielectric constant, which lets it absorb stray oscillations in the range of the interaction waveguide cutoff frequency without significant interaction loss in the range of the operating frequency.
