（重定向自Backward wave tube）

Backward wave oscillator at Stockholm University operating in the Terahertz range

(a) Forward fundamental space harmonic (n=0),
(b) Backward fundamental

A backward wave oscillator (BWO), also called carcinotron (a trade name for tubes manufactured by CSF, now Thales) or backward wave tube, is a vacuum tube that is used to generate microwaves up to the terahertz range. It belongs to the traveling-wave tube family. It is an oscillator with a wide electronic tuning range.
