Cryogenics for the future accelerator complex NICA at JINR.

Summary
NICA (Nuclotron-based Ion Collider fAcility), presently under construction at JINR, will be, upon its completion in 2016, among the most advanced research instruments of the physics community. The facility is aimed at providing collider experiments with heavy ions up to uranium (gold at the beginning stage) with a centre of mass energy up to 11 GeV/u and an average luminosity up to 1027 cm2/s. The NICA cryogenics will be based on the modernized liquid helium plant that was built in the early 90’s for the superconducting synchrotron known as the Nuclotron. The main goals of the modernization are: increasing of the total refrigerator capacity from 4000 W to 8000 W at 4.5 K, making a new distribution system of liquid helium, and ensuring the shortest possible cool down time. These goals will be achieved by means of an additional 1000 l/hour helium liquefier and “satellite” refrigerators located near the accelerator rings. This report describes the design choices of the NICA, demonstrates helium flow diagrams with major new components and briefly informs of the liquid nitrogen system that will be used for shield cooling at 77 K and at the first stage of cooling down of three accelerator rings with the total length of about 1 km and “cold” mass of 220 tons.
