Experimental results obtained in PBX-M suggest that IBW can be used to induce locally a transport barrier and improve core confinement. Using similar neoclassical-like particle and ion energy diffusivity values as inferred inside the IBW-induced core barrier, the CH-mode performance is assessed for TFTR high performance D - T plasmas. By controlling the barrier location, Q-factors in the range can be obtained with a total stored energy of MJ.
