Abstract

In fusion devices, infrared (IR) imaging systems are used routinely for monitoring the surface temperature of plasma-facing components exposed to high heat fluxes in order to prevent and assess potential damages. For a better understanding of the experimental IR measurements, a realistic photonic simulation has been developed from a ray-tracing Monte Carlo code. This simulation has been performed on the IR diagnostic of the existing fusion device Tore Supra in Cadarache (France). First IR simulated images are presented. The similar features of the light between the simulation and experimental data are then emphasized.
