我们报告了由铁电电子枪驱动的 X 波段单级行波管 (TWT) 放大器获得的微波放大行为。在我们的实验中，观察到当二极管电压降至 300 kV 以下时，即使束流仍然很高，行波管的增益也会消失。这种行为被认为与铁电发射的特性有关。
We report behaviors of microwave amplification obtained from an X-band single-stage traveling wave tube (TWT) amplifier driven by a ferroelectric electron gun. In our experiment, it was observed that the gain of the TWT disappeared when the diode voltage dropped below 300 kV, even if the beam current was still high. This behavior is considered to be associated with the characteristics of ferroelectric emission.
