DEVELOPMENT AND PRODUCTION OF SUPERCONDUCTING AND CRYOGENIC EQUIPMENT AND SYSTEMS FOR ACCELERATORS BY IHEP

Superconducting and cryogenic programs at IHEP were got a powerful upsurge in the early eighties of the last century within the framework of the UNK project. More than hundred model superconducting magnets and the pilot batch of UNK superconducting dipoles and four quadrupoles were produced and tested with the help of cryogenic test facilities built for this purpose. Cooperation with international scientific accelerator centers was developed in last ten years. Two superconducting magnetic systems of Electron Lens for the Tevatron accelerator (USA) were developed, manufactured and successfully brought into operation. 42 cryogenic electrical feed boxes of various types for Large Hadron Collider (Switzerland) were developed, produced and put into commission. Results of the development of fast-cycling superconducting magnets for the FAIR project (European Research Centre of Ions and Antiprotons, Germany) are discussed. Description of the largest in Russia cryogenic system for cooling with superfluid helium of superconducting RF separator for the new beam channel of the U-70 accelerator (Russia) is presented. Design and test results of current leads as well as a dipole magnet on basis of High Temperature Superconductor are reviewed.
