Progress in diagnostics for characterization of plasma wall interaction in tokamaks

ITER will operate long discharges (400 s) at high performance (Q = 10) and will have to satisfy strong Safety and Operational limits. This can be achieved only with the control of the plasma wall interactions. New and advanced diagnostics developed in the field of plasma wall interaction such as Infrared Thermography for energy and power fluxes control on Plasma Facing Components and diagnostics for tritium inventory, dust and erosion monitoring are presented.
