Abstract
A device to guide, shape, contain, or concentrate magnetic flux comprises a tube or conduit made of superconducting material to constrain the path of magnetic flux and guide it to a target volume. Below the transition point the material exhibits no resistance to electrical current flow and is impermeable to magnetic flux. In one embodiment, the superconducting material is configured into a cylindrical tube. Upon entrance into the tube the magnetic flux generated by a magnet is constrained to remain between the walls of the tube until it exits the open end where the flux passes through a target volume. In another embodiment, the magnet is situated between two hollow U-shaped arms of superconducting material. The target is situated between the opposite arms of the superconducting material. Magnetic flux generated by the magnet is confined within the U-shaped arms of the superconducting material and passes through the target volume.
