ICRF power levels of up to 2.8 MW were achieved during the 1988 experimental run on TFTR. The central metal impurity concentrations (Ti, Cr, Fe, Ni) and Zeff were monitored during ICRF heating by X-ray pulse height analysis and UV spectroscopy. Antenna phasing was the key variable affecting IRF performance. No increase in metalic impurities was observed for P{approx lt}2.8 MW with the antenna straps phased O-{product}, while measureable increases in titanium (Faraday screen material) were observed for {approx lt}1.0 MW with O-O phasing.
