Abstract—A wide-aperture low-energy electron accelerator based on a high-voltage glow discharge (HVGD) is considered in comparison with accelerators based on a number of longitudinal filaments. The basic design features and advantages of HVGD-based accelerators are presented. These studies showed that it is possible to obtain high values of the density of the electron beam current extracted from the foil (56 µA/cm²) and rather high values of the beam extraction efficiency (35%) in comparison with the previously attained results. The obtained characteristics are comparable with the parameters of the accelerators based on a number of longitudinal filaments. The ability of the accelerator to operate with HVGD is demonstrated both in continuous and pulse–periodic modes without a change in its design. Various ion–electron optical systems of HVGD accelerators have been studied and the advantages of slit-type systems are shown.

基于长丝的加速器高压辉光放电大面积低能电子加速器的比较

摘要—与基于许多纵向细丝的加速器相比，考虑了基于高压辉光放电（HVGD）的大孔径低能量电子加速器。介绍了基于HVGD的加速器的基本设计特征和优势。这些研究表明，可以获得从箔片中提取的电子束电流密度的高值（56 µA / cm ²），与先前获得的结果相比，光束提取效率的值较高（35％）。所获得的特性与基于许多纵向细丝的促进剂的参数相当。加速器与HVGD结合使用的能力在连续模式和脉冲周期模式下均得到了证明，而其设计没有改变。已经研究了HVGD加速器的各种离子电子光学系统，并显示了狭缝型系统的优点。
