Simulation of the Infrared Views of the Upper Port VIS/IR Imaging System of Iter

In fusion devices, infrared (IR) imaging systems are used for measuring the surface temperature of the Plasma Facing Components (PFCs) exposed to high heat flux (~10 to20 MW.m-2). Because in future fusion devices (such as ITER) the carbon PFCs will be replaced by metallic ones with low emissivity, the surface temperature measurement will be much more complicated, requiring optical sensors. Read this white paper to learn the results of realistic photonic simulations we performed using ANSYS SPEOS to predict the global response of the complete system from the sources to the sensor, taking into account the 3D geometry of the ITER environment (tokamak).
