Radiant heat exchange measurements for Tore Supra
Description
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 of T.S. have been simulated in a model with reduced dimensions. In this model, the experiment consists in 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 2500C. Various surface treatments were applied on the two cylinders (mechanical polishing and metal deposition of Al, Ag, Ni)

Pour reduire la depense necessaire au fonctionnement a basses temperatures du systeme cryogenique associe a l'aimant supraconducteur du TOKAMAK TORE-SUPRA, une diminution des echanges de chaleur par rayonnement entre les grandes surfaces des parois chaudes et froides de ce systeme a ete etudiee dans une maquette a echelle reduite. L'experience decrite ici consiste a mesurer, dans cette maquette, l'echange de chaleur, sous vide, entre deux cylindres concentriques en acier inoxydable. L'un des deux cylindres est maintenu a la temperature de 80K. L'autre cylindre, etuvable entre la temperature ambiante et 2500C a recu divers etats de surface soit par polissage, soit par depot de metaux tels que l'aluminium, l'argent ou le nickelFiles
