About a contactless transmission of 10 keV electrons through tapering microchannels

The possibility of increasing the current density of a beam of fast electrons passes through glass cone-shaped channels was demonstrated in. But the fraction of the electrons that passed through the conical channels without loss of the initial energy was not cleared up. Measurements of X-ray spectra generated by transmitted electrons in copper target mounted in vicinity of capillary output were performed for a detailed study of the contactless passage of 10 keV electrons through conical capillarie

Possibility of using dielectric channels as deflecting systems for controlling accelerated electron beams

The results of an investigation of the passage of 10-keV electron beam through dielectric channels fabricated from ceramic (zirconium dioxide) and pyroelectric crystals (lithium niobate) are presented. The angle of deflection of the electron beam by the channels was measured as a function of the angle of interaction of the beam with the internal walls of the channels. The obtained results indicate the possible prospects of using dielectric surfaces as effective deflectors of accelerated charged particl

Passage of 10-keV electrons through a bundle of dielectric channels

Passage of a 10-keV electron beam through a bundle of hollow polysulfone fiber with an inner channel diameter of 160 ± 60 μm was studied. The dependence of the electron beam that passed through the channels on the channel tilt angle with respect to the incident beam axis was measured. The fraction of electrons with an energy loss of less than 10% after passing the channels was also estimate

Compact neutron generators for the calibration of low background experiments

In the coming years, the compact monoenergetic neutron generators (CNG) producing up to 104 n/s may become an alternative to the standard neutron sources based on radioactive isotopes for the calibrations of neutrino and dark matter detector
