New Helium Cryogenic Cooling Technology Enhances Efficiency

Researchers have improved cryogenic cooling methods using helium, developing a technique that either achieves near-absolute zero temperatures 3.5x faster or consumes ~71% less energy than existing technologies. This advancement, detailed in a study published in Nature Communications, primarily enhances the Pulse Tube Refrigerator (PTR), which is essential for a wide range of applications from medical preservation to advanced quantum computing. By optimising the flow and pressure management of helium in the cooling process, the new method not only speeds up cooling times but also reduces helium waste, promising substantial economic and environmental benefits.
