Abstract

The Tore Supra cryogenic connection lines are described. The overall heat losses are given for various levels of temperature. Two types of lines have been constructed with the same general conception. The first set connects the refrigerator to the three satellites. Each line (400 mm diameter and 10 - 22 m long) includes 10 pipes at three temperature levels (80 K, 4.5 K, 1.8 K) with fixed or sliding low-heat-inleak supports. These lines are constructed in 7 modules connected to one another by stainless steel bellows. The second set connects each satellite to 2 adjacent modules with 3 individual coils each. These cryogenic connections retain the same concept as the first, but thermal expansion is taken up by bending rather than by bellows expansion.
