A noninductive current drive concept, based on internal pressure‐driven currents in a low‐aspect‐ratio toroidal geometry, has been demonstrated on the Current Drive Experiment Upgrade (CDX‐U) [Forest et al., Phys. Rev. Lett. 68, 3559 (1992)]

ICRF power levels of up to 2.8 MW were achieved during the 1988 experimental run on TFTR. Metal impurity concentrations (Ti/el, Cr, Fe, Ni) and Zeff were monitored during ICRF heating by X-ray pulse height analysis and UV spectroscopy. Antenna phasin
