Abstract
Recently, reversed magnetic shear operation was performed using only ion-cy clotron-resonance frequency minority heating (ICRH) during current ramp-up. A wide region of reversed magnetic shear has been obtained. For the first time, an electron internal transport barrier sustained by ICRH is observed, with a dramatical drop of density fluctuations. This barrier was maintaine d. on the current flat top, for about 2 a.
