Toroidal variation of power radiated from TFTR

Bolometers located at a number of toroidal and poloidal positions are used to determine the toroidal distribution of impurity radiation losses from the Tokamak Fusion Test Reactor (TFTR) plasmas. Distributions for both OH and beam-heated D+ and He++ plasmas have been determined. The distributions are highly peaked at the limiter sector for plasmas run on the outer limiter but more symmetric toroidally when run on the inner bumper limiter. Plasmas detached from both inner and outer limiters have distributions which are basically symmetric toroidally and poloidally. The widths of toroidally peaked distributions are < or =1 sector of the 20 sector torus. Scalings of the enhanced radiative losses at the limiter with input power are indicated
