| Summary: | The article presents the results of studies of the characteristics of electron flows generated by an electron-optical system with a multi-tip field emitter. Information has been obtained on important beam parameters: the beam current, electron velocity spectrum, pitch factor. The spread in transverse velocity did not exceed 50 % in the studied modes. The shape of the spectra did not depend on the magnitude of the magnetic field and did only weakly on the current in the beam. |
