Abstract :
Gyro-TWA (gyro-travelling wave amplifier) experiments are being undertaken employing a novel helically corrugated waveguide. Numerical and experimental techniques for determination of the waveguide dispersion characteristics are presented. A helically corrugated interaction structure designed and optimized for use with a novel cusp gun in a gyro-amplifier is discussed.
