  1. 15. The Cost of Coolers for Cooling Superconducting Devices from 4.2 to 4.7 K, from 20 to 30 K, and from 65 to 80 K

    Contributed Oral Presentation
    This author and other authors have written papers concerning the cost of refrigeration at liquid helium temperature and higher temperature as a function of the refrigeration delivered. These papers have included small coolers as well. The lowest temperature range from 4.2 K to 4.7 K (the liquid helium temperature range) is covered using coolers that have two stages. The use of magnets and...

  2. 16. Second stage Cooling from a PT-415 Cooler at Second-stage Temperatures up to 125 K with Heat Loads on the First-stage from 0 to 60 W

    CEC-03 - Cryocoolers (Non-Aerospace)
    Contributed Oral Presentation
    The amount of cooling delivered to the second stage of a two stage cooler is dependent on the second stage temperature and the amount of refrigeration provided by the cooler first stage. The second stage cooling as a function of temperature for a Cryomech PT415 cooler (1.5 W at 4.2 K with 42 W on the first stage) has been estimated by scaling similar data that was measured for a Cryomech...

    CEC-03 - Cryocoolers (Non-Aerospace)
    Contributed Oral Presentation
    For the wide spread of high-temperature superconductor (HTS) devices, a cryocooler having COP of >0.1, compact size, light-weight, high efficiency and high reliability is required. For practical use of superconductive devices, especially HTS motor used for electric vehicle. We developed a high efficiency Stirling pulse-tube cryocooler (STP). STP has high reliability and low vibration. However...

  4. 511. R&D status of highly efficient Stirling-type cryocooler for superconducting drive motor
    Mr Jun Watanabe (Kyoto University)

    CEC-03 - Cryocoolers (Non-Aerospace)
    Contributed Oral Presentation
    In this paper, we try to develop highly efficient Stirling-type cryocooler for the next generation drive motor. Target motor is a High Temperature Superconducting Induction/Synchronous Motor (HTS-ISM). Although basic structure of HTS-ISM is almost the same as that of the conventional squirrel-cage induction motor, it can rotate at synchronous speed by use of the superconducting rotor windings....
