Two common ways to cool large superconducting magnets are pool cooling with boiling helium and forced circulation of supercritical helium through hollow conductors. The following three areas of concern are discussed: (1) the substantial void volume inside the conduit may allow some strand motion under the action of the Lorentz force; (2) the helium must be circulated through the conductor, and the pump work dissipated at cryogenic temperatures increases the refrigeration load; and (3) if the conductor quenches, the helium trapped in the long, narrow conductor may briefly experience very high pressure.
