Aa. Golub et al., NUCLEAR DEMAGNETIZATION REFRIGERATOR WITH AUTOMATIC-CONTROL, PICK-UP AND DATA PROCESS SYSTEM, Fizika nizkih temperatur, 21(9), 1995, pp. 974-982
A nuclear demagnetization refrigerator for various physical research a
t ultralow temperatures with automatic control, pick up and data proce
ss system is developed. The design of the main units and performance o
f the refrigerator and automatic system are described. The possibiliti
es of the set-up operation in various regimes are analyzed for the cas
e of NMR investigation of helium quantum crystals.
