Abstract : A method of ion-focusing of an electron beam in a high vacuum is discussed. In order to simplify the electron-optical system, reduce bombarding of the cathode by positive ions, and to insure low heating of the collector, the electron stream is passed through a decelerating electrostatic field. The field gradient is chosen such that the negative space charge is compensated in each cross section of the stream. (Author)
