Abstract
Electron impact excitation of impurity ions is a dominant mechanism for producing the radiation emitted by CTR-type plasmas.1 In addition, the relative intensities of impurity lines excited by electron impact provide a sensitive diagnostic of temperature and density in the plasma. For the densities and temperatures found in magnetically confined plasmas we can assume, as a good approximation, that the ions behave as if they were isolated, and thus neglect any plasma effects on either their structure or their interactions with electrons.
