Travelling-wave tubes (TWTs) are one of the most popular device among vacuum electron devices. TWTs can be used as amplifiers, constituting travelling-wave tube amplifiers (TWTAs), or as oscillators, constituting backward-wave oscillators (BWOs). A BWO is one of the most reliable and spectrally pure...
