The paper presents the results of experimental studies of the passage of electrons through a ceramic macrocapillary with energy of 10 keV in the position when the axis of the channel is parallel to the axis of the incident beam. Measurements were made of the current and energy spectrum of electrons passing through the channel, depending on the value of the current of the beam incident into it and the irradiation time of the channel. The change in the transmission of electrons through the sample as a function of time after the formation of a conductive carbon deposit on the inner surface of both ends of the channel is demonstrated.
The passage of 10 keV electron beam through a bundle of a hollow polysulfone fiber with an inner channel diameter of 160 ± 60 μm was studied. Dependence of a fraction of the electron beam transmitted through the channels on the tilt angle of the channels relative to the incident beam axis is measured. The fraction of electrons that experienced energy losses of less than 10% after passing through the channels was estimated.
