CONSTRUCTION OF ITER COMMON TEST FACILITY FOR CS MODEL COIL

Japan Atomic Energy Research Institute is constructing the Internation al Thermonuclear Experimental Reactor common test facility for the Cen tral Solenoid Model Coil which is around 180 tons, a forced-flow coole d magnet with the maximum pulsed operation of 2 T/s and generates the rated magnetic field of 13 T at 48 kA with stored energy of 668 MJ. Th e test facility consists of a coil vacuum chamber, a cryogenic system with the 5 kW refrigerator and 500-g/s cryogenic pump, two pairs of 50 -kA current leads, two DC power supplies (50kA and 60kA) and two JT-60 pulsed power will be demonstrating the refrigeration and operation of a fusion pulsed magnet and the design and construction will accumulat e experience towards the construction of ITER.
