✦ Synopsis
Cooling techniques based on forced flow He II appear as a possible solution for very large superconducting magnet systems with field strengths in the order of 10 T. To prepare the definition of such cooling systems, a He II test facility of significant size has been built at CEN Grenoble, in collaboration with CERN in Geneva and the EURATOM-CEA fusion research group in Cadarache, France. Its main features are a nearly 230 m long test section, 28 mm in diameter, and mass flow rates of up to 100 g/s of 1.8 K He. First experimental results are presented and compared with solutions predicted by a model calculation.
