Abstract

The build up of impurities in the core of current tokamaks can seriously reduce their fusion performance. These impurities originate in the edge of the tokamak where plasma is in contact with limiters or divertor plates. In this paper an approach to understanding impurity production and transport in the plasma edge based on diagnostic simulation is described. In particular, the important role of Langmuir probes and more advanced electrostatic ion analysers is emphasised. Finally, an example is given of how the method of diagnostic simulation has been used to extract useful information from spectroscopic diagnostics in JET.
