Interpretation of toroidal current and loop voltage temporal evolution during RF-current drive experiment on the T-7 tokamak

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

A simple analytical model is developed and solved to describe time evolution of the loop voltage and toroidal current when RF and inductive current drive take place simultaneously. A relation for the real value of the RF driven current has been obtained under these conditions. Comparison with experimental data from T-7 tokamak allows to estimate the role of the skin effect during RF current drive.
