Abstract :
During operation of present fusion devices, the plasma facing components (PFCs) are submitted to large heat fluxes within a range of 10-20 MW/m2. Understanding and preventing overheating of these components during long pulse discharges is a crucial issue. The surface temperature of the PFCs in the inner chamber of a tokamak is measured by infrared (IR) cameras interfaced with complex optical systems. Due to the complexity of the observed IR scenes and the large amount of data produced, a computer-aided analysis of infrared images will be a key point for ITER, the next fusion device for both real-time applications and deferred-time analysis. This paper describes the current state of IR image analysis based on region of interest (ROI) approach at Tore Supra with an extrapolation to the future ITER tokamak.
