Improved Automate System for Transferring Liquid Helium

An improved automated system for transferring liquid helium from a supply tank to an end-use cryostat has been proposed. Like automated systems developed previously for the same purpose, this system would reduce the time that must be spent by technicians in replenishing cryostats in equipment required to operate for times longer than cryostat holding times. However, relative to prior automated liquid-helium-transfer systems, this system would operate in a more nearly optimum manner so as to reduce the consumption of liquid helium. Examples of equipment with which this system could be used include apparatuses for long-duration scientific experiments and large cooled electromagnets in medical imaging systems
