The IN-mode in the TCV tokamak
A new improved L-mode has been found in TCV with high confinement properties, high edge and global density and no edge temperature barrier. The ohmic IN-modes are presented. They have been obtained in two ways. One thanks to a transient H-mode, even though the plasma is limited, and another with a high reference density at t=0. H98y2 1, H89P=1.6 has been obtained with q95=2.7-3.5, kappa 1.5 and betaN 1.4.
