Abstract

Following serious impurity problems encountered during the initial Alfven Wave Heating experiments in TCA we have tested several new limiters with considerable resulting improvement. Replacing the narrow steel bar limiters by wide, carefully profiled steel limiters led, surprisingly, to a much worse radiation dominated performance. Wide carbon limiters and TiC coated carbon limiters were then installed. The latter gave the lowest Z-eFf but a peaked radiated power profile. We finally installed narrower pure carbon limiters with which the rf experiments could be advanced.
