Abstract :
This paper presents the latest results from a second harmonic gyro-TWA experiment at Strathclyde University. The experiment uses a helically corrugated interaction region and operates at Ka-band. Simulations have been performed to predict the amplifier gain and bandwidth using linear theory. Results from these simulations are compared to laboratory measurements of the cold waveguide dispersion using a new, improved design of polarization converter.
