Mechanisms of metal impurity release during HF-heating in the URAGAN-3 torsatron
Description
Possible mechanisms responsible for the metal impurity release during ICRF production and heating of a plasma are studied with the URAGAN-3 torsatron. It is shown that the edge plasma potential oscillations at the pumping frequency and its harmonics produce an impurity influx from the surface of the helical winding casings (Fe, Cr). The impurity release from the antenna surface (Ti) is caused by a quasisteady ion flux arising in the divertor magnetic flux region during the RF pulse. 21 refs.; 11 figs
