Containment of a Plasma Filament in a Tokamak TO-1 by an Automatic-Control System
Artemenkov L.I. , Kozlov P.I. , Melikhov P.I. , Mukhin P.A., Papkov L.N.
The main discharge characteristics were investigated experimentally in a TO-1 Tokamak without a jacket, in which the plasma filament was kept in equilibrium by an automatic-control system. Three stages of discharge were observed: macroscopically unstable , "free" motion, and contact with the diaphragm. The discharge duration and the energy content of the plasma increase with increasing equivalent time constant of the control winding.
