Abstract

The review starts with a simple introduction to the microwave electronics, and then it addresses the well-known concept of the relativistic electron cyclotron maser (ECM) and the operation principles of the gyrotron devices. The technical review of the gyrotron traveling-wave tube (gyro-TWT) amplifiers focuses on the electron beam-wave interaction schemes and a series of key techniques, including controlling instability competitions by waveguide wall loss, high-power operation based on a higher-order mode, low magnetic field operation on a higher cyclotron harmonic, and broadband operation by employing dispersion shaping. It is revealed that most of the problems in developing a high-power gyro-TWT amplifier are closely related to the instability competitions. Finally, it concludes that overcoming the challenging problem of instability competition in the interaction circuit is the key to promote the development of the high-power gyro-TWT amplifiers.
