Key R&D issues in the field of ITER Diagnostics — •A.J.H. Donne — FOM-Institute for Plasma Physics Rijnhuizen, PO Box 1207, 3430 BE Nieuwegein, The Netherlands

The development of diagnostics for the ITER tokamak is a major challenge. Within the International Tokamak Physics Activity (ITPA), one Topical Group (TG) specialises in diagnostics and aims to support the development of the needed systems. The work of the group includes the identification and development of the requirements for measurements, advising on the selection and design of techniques and on their implementation on ITER, and development of appropriate databases. Several tasks have been identified as ’high priority’ and form the focus of current work: (i) Review of the requirements for measurements of the neutron/ α-particle source profile and assessment of possible methods of measurement (ii) Development of methods of measuring the energy and density distribution of confined and escaping α-particles (iii) Study of the environmental effects on the life-time of first mirrors used in various ITER diagnostics (iv) Assess impact of Radiation Induced Electro-Motive Force (RIEMF) and Radiation Induced Thermo-Electric Sensitivity (RITES) on magnetic measurements and develop methods for the measurement of steady state magnetic fields under ITER conditions (v) Development of diagnostics for the in-situ measurement of dust and study of possible mitigation measures In the presentation a brief overview of the field of ITER diagnostics will be given, with the specific emphasis on a number of the issues listed above.
