Tore Supra (TS) is a Tokamak (Ip=1.5MA, Bt=4T) aiming at doing research in the field of controlled nuclear fusion. It has been constructed with a steady-state magnetic field using superconducting magnets and water-cooled plasma facing components (PFC) for high performances long pulse plasma discharges. When not actively cooled, plasma-facing components can only accumulate a limited amount of energy since the temperature increase continuously during the discharge until radiation cooling is equal to the in coming heat flux.Such an environment is found in the jet Tokamak and on TRIAM. In Torre Supra the surface temperature of the actively cooled plasma facing components reach within a second dteady state. We present here the Tore Supra thermographic system, made of 7 endoscope�s bodies equipped so far with 8 infrared (IR) cameras. It has to be noted that this diagnostic is the first to be actively cooled, designed for steady state. The main purpose of such a diagnostic is to prevent the plasma to damage the actively cooled plasma facing components (ACPFC) which consists of the Toroidal Pumped limiter (TPL), 7m{2}, and of 5 radio-frequency antennae, 1.5m{2} each
