Summary

A simple automatic supply system for liquid helium has been constructed and tested. This is composed of a 100 L liquid container, a cryostat having a vaporizing rate of about 5 L/day, a 1-m long flexible transfer-tube, two solenoid valves, a 5-W electric heater, a container pressure sensor and controller, and two liquid level sensors and controllers. The system has no bypass and valves for cooldown of the transfer tube. Since pressurization of the container is performed through vaporization of liquid by the heater, safety apparatuses have been introduced to prevent over-pressure and heating without liquid. A simple and reliable system operation has been proved by the model experiment and ordinary use.
