Module for new impurity radiation calculations author: H Lux, CCFE, Culham Science Centre author: R Kemp, CCFE, Culham Science Centre author: P J Knight, CCFE, Culham Science Centre N/A This module contains routines for calculating the bremsstrahlung and line radiation of impurities including H and He, assuming a coronal equilibrium.
The model is only valid for T > 30 eV. For some impurity species there is also an upper temperature limit of T < 40 keV.
