Abstract

Stage of plasma initiation is marked out front remaining plasma discharge scenario in tokamak. Plasma as object for control is appear during this stage. Mathematical model of SCENPLINT code for the physical processes description on the stage of plasma initiation is done. Results of comparison between simulations and experimental data on the Russian tokamak T-10 are presented.
