仅提供摘要形式。本文将介绍近年来在等离子体与脉冲功率实验室中对产生强流电子束的被动和主动等离子体源的主要实验研究结果。我们将描述基于闪络等离子体的被动等离子体源（天鹅绒阴极，平板多孔介质）和基于铁电等离子体源（FPS）以及基于FPS辅助的中空阳极等离子体源的主动等离子体源。在这些实验中使用的不同的时间和空间分辨的电，光学和光谱诊断也将被描述。将讨论有关等离子体参数（等离子体密度和温度，等离子体均匀性和等离子体电位）和这些等离子体源（等离子体形成，寿命，真空兼容性）的主要特征的主要数据。此外，我们将讨论所获得的数据有关的电子二极管的操作和参数的产生的电子束，而使用这些等离子体源。
Summary form given only. Main results of recent experimental research of passive and active plasma sources for high-current electron beam generation obtained during the last years in the Plasma & Pulsed Power Laboratory will be reported. We will describe passive plasma sources (velvet cathode, slab porous dielectric) based on a flashover plasma and active plasma sources based on a ferroelectric plasma source (FPS) as well on an FPS-assisted hollow anode plasma source. Different time and space-resolved electrical, optical and spectroscopic diagnostics used in these experiments will be described as well. The main data concerning the plasma parameters (plasma density and temperature, plasma uniformity and plasma potential) and the main features of these plasma sources (plasma formation, life time, vacuum compatibility) will be discussed. Also we will discuss the obtained data concerning electron diode operation and parameters of the generated electron beam while using these plasma sources.
