Summary

A liquid-He-free dilution refrigerator, "mK Cryocooler", for neutron scattering research is constructed. It obtained the lowest sample temperature of 41 mK in the neutron beam experiment. The mK Cryocooler has a pulse tube cryocooler as the 4 K stage and a Joule-Thomson type dilution refrigerator as the mK stage. The mK Cryocooler is a compact and movable refrigerator for neutron scattering research. The obtained cooling power at 100 mK was about 43 microW when the lowest temperature was 49 mK.
