Abstract :
Comparative study is given to the starting current and output power of the coaxial-cavity and cylindrical-cavity gyrotron oscillators operating in the millimeter wave ranges, where the electron-beam misalignment is taken into account. The numerical analysis shows that the coaxial-cavity gyrotron oscillator has lower starting current and less power loss than the cylindrical-cavity gyrotron oscillator when the electron beam has a misalignment to the cavity
