Abstract

In the Uragan-3M (U-3M) and Uragan-2M (U-2M) torsatrons possibilities and prospects of Alfvén method utilization for wall conditioning, plasma production and heating are studied. In U-3M the effect of fast ion loss on H-like mode formation is investigated. In U-2M the wall conditioning associated with the chemical reactivity of the atomic hydrogen to create volatile substances is used. A compact four-strap antenna is proposed for Alfvén resonance heating in U-2M.
