Compact Millimeter-Wave Devices: Dielectric Loaded Carm, High Voltage Carm, Slow Wave Carm and High Harmonic Gyrotron.

摘要

A gyro-BWO can provide broadband slow timescale tunability by adjusting the magnetic field and fast narrowband tunability by varying the gun's voltage. This device depends on the internal feedback of the fast wave interaction between the electron beam's cyclotron resonance wave and a backward electromagnetic wave. Although the previous two experiments were operated at kW power levels, a gyro-BWO is capable of much higher power.
