摘要

本文综述了铁电等离子体源及其应用的研究进展。利用各种诊断方法表明，铁电体的带电粒子发射源是由于不完全表面放电而产生的等离子体。等离子体的形成过程伴随着铁电表面中性离子的解吸。描述了电流幅值为几kA、电子能量高达300 keV的电子束的产生。我们还提供了有关铁电等离子体源的增强发射模式及其作为重离子源的应用的数据。本文还介绍了铁电等离子体源在空心阴极放电、磁控管阴极和反射三极管阴极、大电流开关和高频调制电子束等方面的应用结果。

Ferroelectric plasma sources

We review our studies of ferroelectric plasma sources and their applications. Using various diagnostics it was shown that the source of the charged particle emission from the ferroelectric is a plasma, produced as a result of an incomplete surface discharge. The process of the plasma formation is accompanied by desorption of neutrals from the ferroelectric surface. Generation of electron beams with current amplitude of few kA and electron energy up to 300 keV are described. We also present data concerning an enhanced emission mode of the ferroelectric plasma source and its application as a source of heavy ions. Results of applications of ferroelectric plasma sources in hollow cathode discharge, as cathodes in magnetrons and in reflex triodes, as high-current switches and for generation of high-frequency modulated electron beams are presented as well.
