Electron guiding in macroscopic borosilicate capillaries with large bending angles

Abstract This work presents experiments about the transmission of electrons with an energy of around 15 keV with beam currents up to 20 µA through macroscopic glass capillaries. A systematic study was conducted to experimentally investigate the transmission of electrons through borosilicate glass ca...
