Abstract

The Motional Stark Effect diagnostic is now considered as an essential diagnostic for an accurate determination of current profiles in tokamak discharges. For this reason, this diagnostic is implemented on most of the existing machines. It mainly allows a measurement of the direction of the total magnetic field, a very powerful constraint for the determination of the safety factor profile. On ITER, the knowledge and the control of current profiles will be of crucial importance to realise the long-lasting, high-performance discharges. This is why it was proposed [1] to install a MSE diagnostic on one of the heating beams. The realisation of such a diagnostic on ITER implies to face new challenges, because of the bigger size of the machine and of its hard environment. Now, most of the foreseen difficulties have been examined, solutions envisaged, and we propose to review them in this paper.
