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).

Since last RuPAC five runs of the Nuclotron operation were performed. Diagnostic and control systems were improved. Commissioning of new quench detection system was completed. Deuteron beam was accelerated up to maximum design energy corresponding to 2 T of the dipole magnetic field. Stochastic cooling of coasting deuteron, coasting and bunched carbon beams was obtained. First run with new heavy ion source was performed. Results of these and other works are presented.
