The ITER Cryogenic Lines (CLs) system is a complex network intended to distribute helium at three main nominal temperature levels (4 K, 50 K and 80 K) in order to fulfil the requirements of Cryogenic system end users called clients (mainly magnet feeders (CTBs) and cryopump Cold Valves Boxes (CVBs)). The installation of Cryolines in particular in the Tokamak building is a very challenging and...
As part of the ITER vacuum system’s front end cryo distribution system, 12 complex cryogenic valve boxes (CVBs) and a warm regeneration box (WRB) are required to supply the torus, cryostat (T&C) and neutral beam (NB) cryogenic pumps. This cryogenic distribution system has to operate in a demanding environment within ITER’s main Tokamak building where they will experience high magnetic fields,...
The ITER cryogenic system will be the largest concentrated cryogenic system in the world serving multiple client system (superconducting magnets, plasma fueling and vacuum pumping). Cryogenic technology will be extensively used at ITER to create and maintain low-temperature conditions for vacuum pumping. US ITER is responsible for the design, fabrication, and delivery of the roughing pump...
The paper will present a complete methodology for designing a support system for process pipes in cryogenic multi-channel vacuum insulated transfer lines on the example of a BayonetCan module dedicated to the PIP II accelerator infrastructure at FermiLab. The process of constructing fixed and sliding supports, in particular supports dedicated to cooperation with compensation bellows, will be...
Polish Free Electron Laser facility (PolFEL), presently under construction at National Center for Nuclear Research in Warsaw will consist of electron gun and four cryomodules each housing two 9-cell superconducting TESLA RF cavities. The cryomodules comprising the cavities will be supplied with superfluid helium at 2 K. Other PolFEL cooling power requirements result from the demand of the...
A main distribution box is a large cryogenic valve box which connects two cryoplants with two superconducting linear accelerators (LINACs) of Korean heavy ion accelerator. A major role of the main distribution box is transferring cryogenic helium from the cryoplants to LINACs and controlling flow rate of the helium. It can take other several roles when it encounters special situations. It has...
A new accelerator facility called FAIR is being built at GSI in Germany. The accelerator will accelerate all particles of all the chemical elements. SIS100, the main accelerator ring, requires a cryogenic distribution system that consists of tailor-made (project-specific) multiple helium vacuum-insulated transfer lines and valve boxes. An inside of the required cryogenic equipment and...
The Sanford Underground Research Facility (SURF) will host the Far Detectors of the Deep Underground Neutrino Experiment (DUNE), an international multi-kiloton Long-Baseline neutrino experiment that will be installed about a mile underground in Lead, SD. Detectors will be located inside four cryostats filled with almost 70,000 metric tons of ultrapure liquid argon, with a level of impurities...
