Study of conditions for obtaining quasi-stationary regimes in T-15 MD tokamak

Abstract

The study of conditions for obtaining quasi-stationary scenarios in T-15MD tokamak has been performed. Results of simulation and optimization of T-15MD scenarios with a fully non-inductive current drive using NBICD systems with the power of 6-8 MW, ECCD system with the power ~8 MW and RFCD system with power up to 7-8 MW are presented. It is shown that at the somewhat reduced as compared to the basic value of the toroidal magnetic field Bt ~ 1.5 T in the T-15MD tokamak, discharges can be produced with a fully non-inductive current of about 1 MA, plasma temperature of ~some keV, plasma density of ~(3-7)1019 M-3 and discharge duration of about 20 s. Such discharges are of interest for further experimental study.
