Vacuum electronics technology embraces a wide range of devices, including the traditional multiterminal vacuum tubes, such as triodes, pentodes and beam power tubes, as well as many linear-beam and crossed-field devices, which employ either slow- or fast-wave structures, such as TWTs, klystrons, backward-wave amplifiers and oscillators, gyrotrons, free electron lasers and Cerenkov devices.
