Abstract
We report the experimental study of 1000 eV electrons transported through a tapered borosilicate glass capillary with inlet/outlet diameters of 800 μm/100 μm and a length of 35 mm. Transmission was observed for tilt angles from â9.5° to 1.0°. For tilt angles â9.5° to â4.5° the angular distributions of the normalized intensities of transmitted electrons consisted of a single peak showing stable transmission with inelastic behavior, while for tilt angles closer to zero (â4.0° to â1.0°) the spectrum consisted of two peaks also with an inelastic nature. Interestingly, when the tilt angle was within the range â0.8° to 0°, three peaks were observed, one being the direct peak with only elastic nature, and the other two showing both inelastic and elastic behaviors.
