The technology is a novel configuration for cooling of superconductive magnets used for testing magnets and training personnel. It contains two parts, the cryostat vessel and the recovery vessel. When a quench occurs - loss of superconductivity resulting in a rapid rise of resistance and temperature - in the cryostat the pressure increases because of a restriction on the outgoing line. The liquid helium quickly goes back to the recovery vessel where it is saved for later use. The pressure in the cryostat drops when the quench passes. As a result of the hydrostatic level difference between the vessels and the pressure drop, the cryogen flows back to the cryostat and restarts the cooling.
