摘要

In our previous work[1],using a pair of grooved SiO2 parallel plates,we had obtained stably guided electron beams without energy loss in the incident energy range of 8002 000 V.The very high-current(up to tens or hundreds of nA/mm2)electron beams were adopted.A 128-strip electrode array with a 128-channel picoammeter system[2],combined with an electrostatic deflector were employed to monitor the transmitted electron beams.To better understanding the guiding processes of electron beams passing through the insulting plates,several grooved parallel plates made by different insulating materials were adopted to study the dependence relative to the guiding beams on the conductivities of these materials.As shown in Fig.
