Abstract: | In this paper, the radiation losses of impurity on HL-2A have been simulated by
assuming the profiles electron temperature and density and solving ionization rate
equation under conditions of non-coronal radiation. The time required for an
impurity species to establish equilibrium is proved to be sensitively dependent on
the plasma electron temperature, and it is strongly correlated with the ionization
state distribution during equilibrium establishment of impurity species. It is found
from simulation results that the residence parameter plays an important role in the
enhancement of radiation losses of plasma. |
