Automated precision measurement setups for electrical resistivity of eight metallic samples simultaneously and thermoelectric power of different types of samples in the temperature range of 5–325 K have been developed. The details of the setups and their capabilities have been described. Usually each run takes nearly 5 h and typical error is within 3% and 4%, respectively. The results of high purity Nb and Pt samples are used as examples to demonstrate this.

    We have developed a helium re-liquefier to provide a solution for recovering and liquefying helium vapor from open-loop helium cryostats. The helium re-liquefier is designed to retrofit into the cryostat and form a closed helium loop for the system. The re-liquefier employs a 4 K pulse tube...
