TUCB01	Ultrahigh Vacuum in Superconducting Synchrotrons	vacuum, ion, booster, synchrotron	23

	The achievement of ultrahigh vacuum conditions in the range of 10^-10 – 10^-12 Torr is a very complicate task for charged particle accelerators. For superconducting accelerators the main rest gas is hydrogen which does not freeze effectively on the chamber wall even under the liquid helium temperature. Fast ramp of the magnetic field in the superconducting synchrotrons leads to the heating of the vacuum chamber that brings an additional problem for the achievement of the ultrahigh vacuum. In this talk the review of ultrahigh vacuum systems in superconducting accelerators is presented. Non-evaporated getters under the liquid nitrogen temperature are planned to the achievement of necessary vacuum conditions in the new accelerator complex of the NICA project (JINR, Russia).

	The report overviews the recent SC-related R&D and production activity at IHEP. The scope of the paper extends over the items to follow. Two superconducting magnetic systems of Electron Lens for the Tevatron collider were developed, manufactured and successfully brought into operation. 42 cryogenic electrical feed boxes of various types for the Large Hadron Collider were developed, produced and commissioned. Results of development of fast-cycling SC magnets for the FAIR project are discussed. Operational experience acquired with the largest in Russia cryogenic system for cooling with a superfluid helium of SC RF separator for the beam transfer line #21from the U-70 machine is presented. Test-and-trial results with HTS current leads and dipole magnet employing Bi2223 as well as racetrack coils made of second-generation HTS are reviewed.
