Recent experiments with ECRH and ECCD in T-10

摘要

Experiments with ECRH performed during 1998-2000 are presented. An operating regime with an edge transport barrier, interpreted as the H mode, has been studied with both on-axis and off-axis ECRH. Experimental data imply formation of an internal transport barrier simultaneously with the external transport barrier in the case of off-axis ECRH. Strong evolution of plasma potential in the regions of the external and internal transport barriers has been observed using heavy ion beam probe diagnostics.
