The Cryogenic System

Keeping superconducting magnets cold enough to work.

Role

Magnet cooling

Maturity

Conventional big-science scope

High-temperature superconducting magnets still run at cryogenic temperatures; a helium refrigeration plant maintains the cold mass and intercepts heat loads. The cryoplant is a major, conventional balance-of-plant system with well-understood scaling.

Cryogenics is treated as a ready-for-detailed-design system in the construction-readiness review — a solved problem class rather than an open gate.
