Hybrid Cryogenic Refrigerator: Combination of Brayton Magnetic-Cooling and Gifford-McMahon Gas-Cooling System

We propose a new cryogenic refrigerator which is a hybrid of the Brayton magnetic-cooling cycle and the Gifford-McMahon (GM) gas-cooling cycle. We evaluate the refrigeration power of the refrigerator with ErNi regenerator material by a numerical simulation. The results show a remarkably high refrige...

Zusammenfassung:We propose a new cryogenic refrigerator which is a hybrid of the Brayton magnetic-cooling cycle and the Gifford-McMahon (GM) gas-cooling cycle. We evaluate the refrigeration power of the refrigerator with ErNi regenerator material by a numerical simulation. The results show a remarkably high refrigeration power in contrast to the conventional simple GM gas-refrigerator.
