About a contactless transmission of 10 keV electrons through tapering microchannels

Abstract

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
