Système cryogénique du Nuclotron : état actuel et développements récents.

Nuclotron cryogenic system: status and recent development.


The Nuclotron is the first fast cycling superconducting synchrotron intended for the acceleration of high-energy nuclei and heavy ions. The accelerator was put into operation eleven years ago at the Joint Institute for Nuclear Research in Dubna near Moscow. The cryogenic system of the Nuclotron includes three helium refrigerators. Each of them has a nominal capacity of 2000 W at 4.5 K. These refrigerators cool the accelerator ring, which has a perimeter of 251.5 m and a "cold" mass of about 80 tons. The new technical ideas used at the Nuclotron have provided low cost of its refrigeration, high reliability, good thermodynamic efficiency, and the ability to regulate the refrigeration capacity. The long-term experience and novel technical solutions of the Nuclotron cryogenic system are described.
