|Abstract:||In ITER, alpha particle loss measurements remain difficult and further progress is needed. A number of standard measurement methods have been proposed but techniques capable of operating in the fusion reactor conditions need development. The charged particle activation method is a novel concept demonstrated only recently on JET and its feasibility for performing measurements in ITER is being investigated. This design study presents the first detailed activation calculations in order to derive the diagnostic response and expected performance. The calculations were carried out using the activation inventory code FISPACT-2007 and the EAF-2007 nuclear data libraries. The results indicate that ITER Baseline requirements may be fulfilled and in-situ measurements may be performed in an equatorial port plug. The main constraints and parameters are described. Finally, research needs for further diagnostic development are outlined.|
