The identification of impurities and the investigations into their behaviour in magnetically confined plasmas, as well as the plasma parameter determination, are amongst the most important applications of X-ray spectroscopy in the JET and ASDEX tokamaks. Broad-band flat crystal monochromators - supported by impurity monitors and calibration devices - enable impurity concentration and plasma radiation loss measurements over a wide range of atomic numbers, while high-resolution spectroscopy can provide plasma ion temperature and rotation measurements.
