We have developed closed cycle liquid helium refrigerators using a Joule Thomson circuit precooled by commercially available two staged Gifford Mac Mahon cryocoolers. The Joule Thomson counterflow heat exchangers are modular and have been thermo-hydraulically characterized. Fully automatic cool down

Several different means of connecting small closed cycle refrigerators to liquid helium cryostats for the purpose of reliquefying the boiloff or reducing the boiloff rate are described Interface principles which enhance the reliability and serviceability are presented. Most of the interfaces which a
The design of a low temperature cryostat suitable for accelerator based radiation damage studies is presented. The system employs a commercial two-stage closed cycle helium gas cryorefrigerator and a mechanical heat switch to permit sample irradiations at 13-15 K and rapid temperatures cycling up to
