Abstract

In the TCV tokamak, it is possible to create steady-state discharges with full current replacement by electron cyclotron current drive (ECCD). In this work, we estimate the EC driven current with various launching angles and compare experimental and theoretical methods to reveal the ECCD component. Also, differences between experimental and theoretical values of current drive efficiency and plasma conductivity are discussed in discharges with a small or vanishing induced electric field.
