4. High-temperature superconductor applications
4.1 Cryogenics and energy
4.1.1 Cryogenic systems and performance
The critical temperature of all known superconductors operating at ambient pressure is below room temperature. Cryogenic systems are therefore used to cool them, either liquefied gases (essentially liquid helium at T = 4.2 K and liquefied nitrogen at T = 77 K), or refrigerated thermal machines. The latter are based on various thermodynamic cycles, either "recuperative", such as Joule-Thomson or Brayton systems (the fluid always circulates in the...
