CS Model Coil Test Facility

Abstract

To demonstrate the superconducting magnet technology applicable for the construction of the International Thermonuclear Experimental Reactor (ITER), a model coil simulating the ITER central solenoid coil has been fabricated. In this way, the world's largest superconducting pulse coil with supercritical helium forced-flow cooling was realized. To test the model coil, the Japan Atomic Energy Research Institute has developed and constructed a large superconducting coil test facility named the CS model coil test facility. This facility has a large power supply system with a maximum capacity of 225MVA and a 5kW helium cryogenic system with a 1.0kg supercritical helium circulation system, which is the world's largest superconducting test facility. Design features, specifications, and performances of the CS model coil test facility are described.
