DRY NUCLEAR DEMAGNETIZATION CRYOSTAT
Based on BlueFors model BF-LD400 dilution refrigerator with 9T superconducting magnet.
Characteristics of dilution unit:
- Base temperature: 7 mK,
- Cooling power mixing chamber (100 mK): 550 μW.
The experimental cell for liquid 3He (0.6 mol) is embedded inside the top part of the nuclear demagnetization stage. The refrigerator cools 3He in the experimental cell down to 160 μK.
Location: Room 154b and room 155b.
