Plasma production using microwave and radiofrequency sources

This paper is devoted to the plasma production by microwave and RF sources in magnetic trays. It is shown that microwaves with frequencies at the fundamental electron cyclotron resonance can be used for this purpose. Waves with frequencies of a few megahertz have been used to produce plasmas at the Uragan-3 device at KFTI. Qualitative agreement was found between the results of these experiments and the analytic predictions were presented in this paper. (author). 5 refs, 2 figs
