Plasma electron and ion sources based on low pressure glow and arc

This paper reviews last achievements in a field of investigation phenomena of electron and ion emission from plasma as well as in designing of high current broad beam plasma cathode electron and ion sources. The presented results were obtained in the Tomsk research group, which is well-known by the fundamental investigation in this kind of plasma physics and by creation of the sources with the top record parameters. Some of presented results are a product of collaboration between Tomsk group and the other laboratories (GSI, Darmstadt, Germany; LBL, Univ. of California, Berkeley)
