Abstract

Metal impurity (Ni, Fe, Cr) line emission from TFR plasmas with graphite limiters has been studied during both the ohmic heating phase and supplementary heatings (either neutral beam injection or ion - cyclotron resonance heating). The experimental results have been compared with the predictions of an impurity transport numerical simulation code. It has thus been possible to evaluate the central metal ion density, the central radiated power density, and the total radiated power. It is concluded that, at the present time, metal impurity radiation losses can be neglected in the discharge power balance.
