1 JT-60SA *1, *1 *1 *1 Frederic MICHEL *2 Christine HOA *2 Manfred WANNER *3 Cryogenic System for JT-60SA Specialization of the cryogenic system for superconducting magnets of a tokamak device Kiyoshi YOSHIDA *1,, Kyohei NATSUME *1, Kaname KIZU *1, Yoshihiko KOIDE *1, Frederic MICHEL *2, Christine HOA *2 and Manfred WANNER *3 Synopsis: The mission of JT-60SA is to contribute to the early realization of fusion energy by addressing key physics issues relevant for ITER under the Broader Approach activities jointly undertaken by Japan and Europe. JT-60SA is a complete superconducting tokamak capable of 5.5 MA plasmas during 100 s, which is closest to ITER plasma conditions. The cryogenic system for JT-60SA will cool the superconducting magnet system (4.4 K), the high-temperature superconductor (HTS) current leads (50 K) the thermal shields (80 K), and the cryopumps (3.7 K). The cryogenic system including the warm compression station, the gas storage units, the refrigerator cold box (RCB) and the auxiliary cold box (ACB) was manufactured in Europe. It is installed at the JAEA Naka site by Keywords: superconducting, magnet, cryogenic, helium, refrigerator (Some figures in this article may appear in color only in the electronic version) JT-60SA ITER 1) EU 2, 3) EU EU TF 4) 5) 6) CS 7) EF 8) 9) 10) JT-60SA CEA *1 *2 *3 Received September 7, Japan Atomic Energy Agency, Naka Fusion Institute, Mukoyama, Naka, Ibaraki , Japan CEA, INAC-SBT, 17 rue des Martyrs Grenoble Cedex 9, France Fusion for Energy, Broader Fusion Development Department, Boltzmannstr 2, Garching, 85748, Germany yoshida.kiyoshi56@jaea.go.jp DOI : /jcsj EU JT-60SA RCB ACB EU EU 11, 12) 13) 4.5 K 9 kw EU 14, 15)
