AI Thread Summary
Ultra low cooling methods below 1K, specifically cryostat cooling using Helium-3 (HE3) and nuclear diamagnetisation, present distinct advantages and disadvantages. HE3 cooling is known for its efficiency and ability to reach lower temperatures, but it can be expensive and complex to operate. In contrast, nuclear diamagnetisation offers a simpler setup and can achieve low temperatures without the need for cryogenic fluids, though it may not reach as low a temperature as HE3. The choice between these methods often depends on specific experimental requirements and budget constraints. Understanding these factors is crucial for researchers in fields requiring ultra low temperature environments.
