Abstract:An industrial-scale helium II refrigeration plant operating at 1.8 K with a low specific energy consumption (436 kWel for 370 W effective refrigeration) was built to cool superconducting components of particle accelerators and separators. The performance, process, control system, and important aggregates are described; the plant is compared with similar plants built previously.
