Study of MARFE Phenomena on HT-7 Tokamak

摘要

MARFE phenomena on HT-7 tokamak is studied in this paper. A best correlation has been found between the total input ohmic power and the product of the edge line average density and Z_eff. MARFEs which is strongly correlated with impurity density, always occurs at Z_eff=3～8 ohmic discharge.
