Abstract
Processes accompanying in the tokamak discharge shutdown were studied by injecting a large number of heavy-impurity (KCl) pellets (∼1019 atoms) into the T-10 tokamak operating in the ohmic regime. A more than twofold drop in the current at an average rate of 12 MA/s was observed, which corresponded to a considerable (exceeding 75%) decrease in the magnetic energy of the plasma column. The observed phenomena showed evidence of the production of runaway electrons during the discharge current drop.
