One of the problems encountered in thermonuclear fusion research is with the presence of elements other than hydrogen isotopes in the plasmas created for these studies, and the effects of such impurities on plasma behaviour. As a result, atomic physics has played an important role in the investigation of plasma properties and behaviour ever since the early days of fusion research. With the tokamak device as an example, some characteristic features of the spectra arising in such plasmas are reviewed. The use of the emitted lines for localised plasma diagnostics is discussed. Some specific examples of diagnostic applications are given, including influx measurements, impurity concentrations and Doppler measurements.
