 | Microkelvin FacilitiesThe facilities consist of three experimental bays: two housing copper nuclear demagnetization refrigerators completed in 1989, and the third containing a PrNi5 nuclear refrigerator completed in 1994 as part of the National High Magnetic Field Laboratory (NHMFL). Today, Bay 2 and Bay 3 are operated as the NHMFL High B/T Facility and open to all qualified users worldwide. |
| Special Features |  |
| A number of innovative design features have been developed for the Microkelvin facility to provide an ultra-quiet environment needed for experimental research below milliKelvin temperatures.
⚹ Each bay accommodates a 15-foot dewar that is supported by a 13-foot concrete tripod whose feet are anchored in 5-ton concrete blocks independent of the building in order to isolate the research apparatus from mechanical vibrations. ⚹ Generators in the facility exclusively supply clean uninterrupted electrical power for measurements. ⚹ Liquid helium levels and the rates of helium boil-off in all dewars are monitored continuously via Cryonet. The monitoring provides a measure of safety in case of magnet or dewar malfunction. Liquid helium is supplied to the research stations by UF Cryogenic Services as needed. |
