Numerical studies of impurities in fusion plasmas

摘要: The coupled partial differential equations used to describe the behavior of impurity ions in magnetically confined controlled fusion plasmas require numerical solution for cases practical interest. Computer codes developed modeling at Princeton Plasma Physics Laboratory are as examples types employed this purpose. These solve density each charge state and their associated radiation rates using atomic physics appropriate these low-density high-temperature plasmas. simpler local zero spatial dimensions while more complex that explicitly include transport simultaneously with processes ionization recombination.
