Experimental provision

1. Refrigerators for ultralow temperature physical research:

* a refrigerator for nuclear demagnetization of copper (~ 22 moles) for T < 1 mK temperature level;

* a dilution refrigerator with a hybrid circulation system (Tmin ~ 5 mK);

* a dilution refrigerator with a condensation-sorption pumping system (Tmin ~ 10 mK);

* a dilution refrigerator with outer circulation (Tmin ~ 15 mK);

* evaporation refrigerators with 3He (Tmin ~ 0.3 mK).

2. Physical research techniques:

* impulse nuclear magnetic resonance;

* acoustic methods;

* precision barometry;

* non-contact measurement of conductivity of low-dimensional electron systems over liquid helium;

* determination of concentration in superfluid mixtures from permittivity measurements.
