Abstract

With a careful choice of the viewing parameters, neutral-particle analysers could be used to detect small changes in the radial electric field E_r immediately next to the separatrix with a submillisecond (50-100 µs) resolution. In particular, the poloidal viewing angle has to be optimized according to the ripple- and plasma geometry. In addition, the use of a small diagnostic beam is proposed to improve the signal level and quality.
