    摘要： An electron beam generator which can operate in pulse or continuous mode, has an electron beam which is emitted in a main electron gun including a thermionic cathode and an anode. Used in association with this main electron gun is an auxiliary electron gun including a cathode, a grid intended to modulate an auxiliary electron beam in pulses when it is operating in pulse mode or to adjust the current of the auxiliary electron beam when it is operating in continuous mode, and an anode. The anode is in thermal and electric contact with the cathode of the main electron gun. The auxiliary electron beam controls the emission from the cathode. The electron beam emitted by the main electron gun is not disturbed by crossing the grid. Application of the electron beam generator is notably to microwave longitudinal interaction tubes operating at high average and/or peak power.
