In this frame, the influence of emitter surface roughness, emission inhomogeneity, and secondary electron generation on gyrotron operation is presented, with focus on Low Frequency Oscillations (LFOs) and Electron Beam Halo (EBH) generation.StrahlsystemeEmitterLow Frequency OscillationsMagnetron Injection GunGyrotronElectron Beam HaloElectron Beam HaloGyrotronZhang Jianghuaauth1292461BOOK9910346767903321Influence of Emitter Surface Roughness and Emission Inhomogeneity on Efficiency and Stability of High Power Fusion Gyrotrons3022338UNINA
