Commissioning Status of the Technical Equipment at the Compressor Station CS 2 of the Veksler Baldin Laboratory of High Energy Physics

Commissioning of the new superconducting accelerators (Booster and Collider) required more than doubling the cooling capacity of the VBLHEP’s cryogenic system. Two new Kaskad-110/30 screw helium compressors Nos. 3 and 4 have been installed at the compressor station CS No. 2 to supply compressed helium to the liquefier OG-1000 and satellite refrigerators RSG-2000/4.5 Nos. 1–3. In addition, a new closed cycle nitrogen cryogenic system of the accelerator NICA complex is currently under construction, which is intended for the production of liquid nitrogen, recondensation of nitrogen vapors, and supply of nitrogen of the consumers. Two Samsung SM5000 turbocompressors Nos. 1 and 2 and an Aerocom 2-179/18 turbocompressor will be used to supply compressed nitrogen to the cryogenic facilities.
