+In this type of refrigerators the helium bath does not surround the lower part of the cryostat. Radiation shields enclose the lower section. The refrigerator shown here (named "DRILL") was developed by CNRS and ILL in Grenoble (H. Godfrin, C. Gianèse and R. Chung ). It also has a LN2 bath for long operation time between helium transfers.
