A dilution refrigerator with a cooling power of 500 #W/100 mK combined with a superconducting magnet of up to 13.5 T has been developed for measurement of the acoustic de Haas-van Alphen effect for heavy fermion compounds. A sample was immersed in a liquid 3He -aHe mixture in the tail of the mixing
exchanger for a dilution refrigerator with a high thermal efficiency is presented. Discrete heat exchangers with by-pass channels were used to decrease the flow impedance. This heat exchanger was designed so that the thermal conductance of liquid along the stream was greatly reduced. The effective t
