摘要

The characteristics of charge deposited (time) into a tapered glass capillary were studied for an incident energy of similar to 1025 eV at a tilt angle of 5 degrees. Electron beams resulting in intensities of 1.5-7000 nC deposited into a tapered borosilicate glass capillary were investigated for inlet/outlet diameters of 800/100 mu m. The electron transmission consisted of stable transmission, fluctuations, blocking and self-discharging associated with a sudden rise of transmission as deposited charge was ejected from the capillary. In the case of stable transmission, it was found to be due to both elastic and inelastic contributions, with inelastic transmission dominant.
