An implicit Monte Carlo method for simulation of impurity transport in divertor plasma
A new implicit Monte Carlo (IMC) method has been developed to simulate ionization and recombination processes of impurity ions in divertor plasmas. The IMC method takes into account many ionization and recombination processes during a time step. We incorporate this method into a one-dimensional impurity transport model. In this transport calculation, impurity ions are followed with the time step about 10 times larger than that used in conventional methods. The average charge state of impurities and the radiative cooling rate are calculated at the electron temperature.
