Simulation of radiation losses using non-coronal model on HL-2A

doi:10.1088/1009-1963/15/12/038

Abstract

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.

Keywords: ionization rate equation radiation losses radiated power coefficient residence parameter
