先前提出的方法，它使得馈送和提取微波辐射的回旋行波管（gyro-TWT），使用一个单一的高度超大的屏障窗口已经被实验证明。Ka波段回旋行波管使用螺旋波纹波导，在阴极侧由反射器和在收集器侧的偏振器界定，并且在输出传输线的开始处还具有偏振分离器，在零驱动驱动稳定状态下产生了具有2.1GHz的-3-dB带宽的6 kW CW功率，并且在频率锁定状态下产生了约9 kW功率。
A previously proposed method, which enables feeding and extraction of microwave radiation to and from gyrotron traveling wave tubes (gyro-TWTs) using a single highly oversized barrier window has been experimentally proven. A Ka-band gyroTWT using a helically corrugated waveguide bounded by a reflector at the cathode side and a polarizer at the collector side and also having a polarization separator at the beginning of the output transmission line has produced 6 kW CW power with -3-dB bandwidth of 2.1 GHz in the zero-drive-drive stable regime and about 9 kW power in the frequency locking regime.
