MEASUREMENT OF HEAT EXCHANGE BY RADIATION IN TORE-SUPRA
In order to minimize the energy consumption of the low temperature cryogenic system connected to the superconducting magnet of TORE-SUPRA, heat exchange from thermal radiation between the vacuum vessels and the thermal shields has been studied. Accordingly, large- scale cold and hot walls have been simulated in a model with reduced dimensions. In this model, the experiment consists of the measurement of the thermal radiated power between two concentric cylindrical surfaces of stainless steel under vacuum conditions. The temperature of the external cylinder was kept constant at 80 K. The internal cylinder was bakeable up to 250 degrees C. Various surface treatments were applied on the two cylinders (mechanical polishing and metal deposition of Al, Ag, Ni).
