摘要： The pulse mode electron generator of the invention includes a field emission cathode with electron-emitting micropoints associated with a grid biased by means for positively biasing the grid and an anode attracting electrons emitted by the cathode. The grid is biased by a permanent positive pre-bias voltage generator delivering a rest voltage which is slightly lower than the emission threshold voltage of the cathode and in series with a positive pulse voltage generator delivering a pulse component of sufficient value to exceed the emission threshold voltage of the cathode. This facilitates the pulse mode production of electrons and reduces the power consumption needed to produce the electrons.
