COMPACT ADIABATIC DEMAGNETIZATION REFRIGERATION STAGE WITH INTEGRAL GAS-GAP HEAT SWITCH

摘要

An adiabatic demagnetization refrigeration stage includes a salt pill, a magnet surrounding the salt pill, and a gas-gap heat switch interposed between the salt pill and the magnet. A method of operating an adiabatic demagnetization refrigeration stage includes using a magnet surrounding a salt pill to apply an increasing magnetic field to the salt pill, producing a gas to activate a gas gap heat switch interposed between the magnet and the salt pill to provide a path for heat flow from the salt pill through the magnet to a heat sink, and decreasing the magnetic field applied to the salt pill while adsorbing the gas to de-activate the gas gap heat switch to cool the salt pill to a lower temperature and cool an object attached to a cold tip extending from the salt pill.
