Kelvinox 400 HA is a 3He-4He dilution refrigerator manufactured by Oxford Instruments from Great Britain. The purchase was made as part of a grant from the Polish Ministry of Science and Higher Education. It is an ultra-high vacuum system equipped with a air-lock that allows the sample to be introduced directly into the measuring space without the need to heat the cryostat to room temperature.
Experimental setups for:
- dilatometric measurements as a function of temperature, magnetic field and angle (using piezoelectric rotators)
- thermoelectric power (Seebeck and Nernst effects)
- Hall magnetometry
- electrical resistance and Hall effect
Basic Specification
- base temperature Tb ≤ 7 mK
- magnetic field B ≤ 16 T
- compensation zone
- experimental space Φ < 63 mm
- high resolution rotation control Δθ < 0.05 deg
