Abstract

The linear and the nonlinear analyses have been performed for the Electron-Cyclotron Maser interaction, between arbitrary rf field modes (TM, TE, HE or EH) and an axial velocity electron beam. This interaction [1-2] is capable of giving wave growth, with a conversion efficiency as high as 100% in principle. The underlying idea is based on the observation that for a wave field with transverse components (E₁,B₁), if the axial electron velocity initially satisfies v > E₁ / B₁ which requires that q = E₁ / cB₁ < 1, then transverse electron momentum is produced coparallel to the wave electric field, with the resulting current doing work on the wave, while the resonance is maintained with an appropriate value of the uniform axial magnetostatic field B₀.
