Abstract
PURPOSE:To improve the thermal efficiency of a cooling system by passing helium gas in total weight brought to a supercritical pressure in series with a superconducting magnet and current leads, returning the gas to a helium liquefying refrigerator under a low-temperature state after peripheral current leads are cooled and returning the gas to a low-temperature line. CONSTITUTION:A superconducting magnet 14 is supplied with supercritical helium gas in total weight from a super-critical helium generator 13 and the same magnet 14 is cooled, total weight is fed continuously into double-side current leads 17, 18, and the gas cools the current leads, and is recovered to a low-pressure line hot end section 22a for a J-T type heat exchanger 22 through insulating couplings 19, 19, low-temperature valves 20, 20 and a refrigerant transfer pipe 21. Helium gas immediately after the gas cools the superconducting magnet 14 is brought to approximately 6K, and brought to a temperature state of approximately 11.5K at a stage after it passes through the current leads 17, 18 from the magnet 14 and cools the current leads in order to maintain the thermal shield of 80K of said current leads 17, 18. The sensible heat of helium gas is recovered to a cooling system without waste, thus extremely improving thermal efficiency.
