Topic — A tokamak plasma impurities code
Description
Title of program: TOPIC Catalogue Id: ACDY_v1_0 Nature of problem In high temperature low density tokamak plasmas, radiation cooling by impurity atoms can be an important energy loss mechanism, since radiation is not reabsorbed. The coupled set of time-dependent diffusion equations for ionized tokamak plasma impurities is solved in conjunction with a simple model for neutral impurities, on the assumption of a cylindrical symmetry. The resultant density distributions are used in the subsequent computation of the related energy losses.
