APPLICATION OF IBW-INDUCED TRANSPORT BARRIER IN TFTR

Experimental results obtained in PBX-M suggest that IBW can be used to induce locally a transport barrier and improve core confinement. Usin g similar neoclassical-like particle and ion energy diffusivity values as inferred inside the IBW-induced core barrier, the CH-mode performa nce is assessed for TFTR high performance D-T plasmas. By controlling the barrier location, Q-factors in the less than or equal to 0.6 range can be obtained with a total stored energy of less than or equal to 6 MJ.
