Role of radiation loss In transport processes in self-organized plasmas in toroidal devices
At many tokamaks, plasma energy confinement improves after impurities are injected and increased radiation loss is observed. We have experimentally studied whether this effect is observed at the L-2M stellarator. We ascertained that at L-2M, over a range of operating parameters, the energy lifetime does not depend on the radiation loss power. We analyzed plasma confinement in L-2M in the ECRH regimes at different powers of radiation loss. Analysis of the data obtained at L-2M made it possible to advance a hypothesis concerning the mechanism for improving plasma confinement in tokamaks when there is increasing radiation loss. .………………………..… 1
