Summary

Cryogenics is a key technology for cooling the superconducting magnets in the future fusion machines. Large refrigeration and distribution systems supply helium at different temperature levels from BOK to 3.6K, in various operating modes. One of the main challenges is to design and to operate safely and reliably the system in order to smooth the thermalloads which are highly variable with time due to the cycling plasma operation. This article describes the cryogenic system of the tokamak JT-60SA installed in Japan. The main results of the reception tests are presented.
