  To obtain an ultrahigh vacuum, it is necessary to preliminarily degass the "warm" sections of the vacuum system of accelerators by prolonged heating to remove water vapor and molecules of other substances adsorbed on the inner surface of the walls of the vacuum chamber. The presented system allows you to heat products with a known unknown heat capacity and thermal conductivity. Some of the accelerators of the NICA complex are supplied without their own heating system and heating is carried out by specialists directly at the accelerator site.

  New accelerator complex is being constructed by Joint Institute for Nuclear Research (Dubna, Russia) in frame of Nuclotron-based Ion Collider fAcility (NICA) project. The NICA layout includes new Booster and existing Nuclotron synchrotrons as parts of the heavy ion injection chain of the NICA Collider as well as beam transport lines which are the important link for the whole accelerator facility. Designs and current status of beam transfer systems in the beginning part of the NICA complex, which are partially commissioned, are presented in this paper.

  The heavy ion NICA collider has three types of the vacuum volumes: insulating vacuum volume of superconducting magnet lattice; the cold beam pipe inside SC-magnets with operating temperature from 4.2 K to 80 K; the warm beam volume at the room temperature inside the insertion and experimental regions with RF stations, beam cooling station, diagnostic equipment and etc. The vacuum requirements, design of three vacuum systems, problems and paths of their decision for achievement ultra-high vacuum are described.
