In high-energy physics, Nb-Ti-based superconducting magnets are traditionally cooled below 5 K using complex, large-scale cryogenic helium plants. However, for small-scale test facilities without access to such infrastructure, or for mobile superconducting magnet-based detectors, compact cryocoolers offer a promising alternative. The primary challenge of this approach is their limited cooling...

According to Landau’s two fluid description, heat transport in He II results from the relative motion of the entropy carrying normal component and the inviscid superfluid component. At sufficiently high relative velocities, quantised vortex lines form a turbulent tangle that produces mutual friction between the two components. In reduced engineering descriptions, this interaction is commonly...
