In cryogenics, like all other fields in the known universe, heat flows from a hotter region to a colder region if there are two different temperatures and some physical proximity or connection between the two. How to preserve and efficiently use the “cold”, in other words directing or redirecting, orga­nizing or orchestrating, and promoting or inhibiting this flow of heat, is the job of cryogenic heat management. Heat management is central to designing and operating cryogenic systems that will function and work safely and efficiently. The range of systems includes, although not exclusively, systems such as superconducting magnets and cavities for MRI, high-energy physics, fusion (toka­mak), and free electron laser systems; space launch and exploration; energy and transportation use of liquid hydrogen; transportation and storage of liquefied gases; and food preservation, as well as potential future applications in cryo-life-sciences and chemical industries.
