Abstract
[[abstract]]A saturated instantaneous bandwidth (FWHM) of at least 10% in a Ka-band gyrotron traveling-wave tube (gyro-TWT) with uniform interaction waveguide and magnetic field was obtained. A relatively low α(≡ν⊥/ν∥) beam has resulted in stable saturated operation and broad bandwidth. This, together with the overall performance of the tube (18.4-kW maximum power at 18.6% efficiency and 18-dB gain), strongly reinforces the possibility of developing a new generation of millimeter traveling-wave amplifiers based on the gyro-TWT[[fileno]]2010126010102[[department]]物理This publication has 6 references indexed in Scilit:
