A liquid helium tank is a specialized container designed to store and transport liquid helium, a cryogenic fluid that remains in a liquid state at extremely low temperatures. These tanks are typically made from materials that can withstand the cold and are insulated to minimize heat transfer, which helps maintain the low temperature required for helium to remain liquid. Liquid helium is commonly used in various applications, including cooling superconducting magnets in MRI machines and particle accelerators. The tanks are equipped with safety features to prevent pressure buildup and ensure safe handling, making them essential in scientific and medical fields where cryogenic temperatures are necessary.
