Abstract

Input couplers for mm-wave gyrotron traveling wave amplifiers (gyro-TWAs) were designed. A W-band input coupler composed of a T-junction and a broadband reflector was constructed and measured in W-band. It achieved a transmission coefficient of -2.2 dB including the pillbox window and a waveguide bend. A multiple-hole coupler was designed and simulated at 372 GHz. Without considering the Ohmic loss, in simulations the 372GHz coupler achieved a transmission coefficient of -0.5 dB.
