Shielded Superconducting Linear Motor for Towed-Grid Studies of Quantum Turbulence

A motor is described which can pull a grid through a channel of pure superfluid 4He to produce homogeneous isotropic turbulence. The motor is composed of a superconducting solenoid inside a superconducting shield to minimize Joule and eddy current heating of the liquid helium. Computer simulations s...

Description
Summary:A motor is described which can pull a grid through a channel of pure superfluid 4He to produce homogeneous isotropic turbulence. The motor is composed of a superconducting solenoid inside a superconducting shield to minimize Joule and eddy current heating of the liquid helium. Computer simulations show the design to be feasible.
