Abstract
Ion temperature and velocity distribution functions, ion densities, plasma rotation velocities and magnetic fields have been identified by the ITER design team as key parameters1, for which spatially-resolved profiles with medium time resolution are of vital importance in three major areas. These are: machine protection and plasma control, evaluation and optimisation of plasma performance, and investigation of the physical phenomena which might limit ITER’s performance. Only a diagnostic based on active-charge-exchange (CXRS) and beam-emission spectroscopy (BES), using a dedicated neutral beam, can provide all these data with the accuracy and resolution required (table 1).
