  1. 268. Development of cryogenic installations for large liquid argon based neutrino detectors
    Johan Bremer (CERN)
    29/06/2015, 09:00
    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Poster Presentation
    A proposal for a very large liquid argon (40 kt) based neutrino detector is being studied. To validate the design principles and detector technology, and to gain experience in the development of the cryostats and the cryogenic systems needed for such large experiments, several smaller scale installations will be developed and implemented, at Fermilab and CERN. A small-scale prototype (35 t)...

  2. 142. HTS cooling below 60 K with two-stage mixed-refrigerant cascades using low-flammability mixtures
    Mr Thomas M. Kochenburger (Karlsruhe Institute of Technology, Institute for Technical Thermodynamics and Refrigeration)
    29/06/2015, 09:00
    CEC-09 - Cryogenics for Power Applications, Energy, Fuels and Transportation
    Poster Presentation
    High-temperature superconductors offer new perspectives for efficient transportation of electrical energy in urban and industrial power grids. The size of the components is in many cases limited by the available refrigeration technology. In the operating temperature range of 65 – 70 K, cooling is presently achieved by liquid nitrogen, turbo-Brayton plants or batteries of regenerative...

  3. 131. Performance Test of the Cryogenic Cooling System for the Superconducting Fault Current Limiter
    Dr Yong-Ju Hong Hong (Korea Institute of Machinery & Materials)
    29/06/2015, 09:00
    CEC-09 - Cryogenics for Power Applications, Energy, Fuels and Transportation
    Poster Presentation
    The Superconducting Fault Current Limiter (SFCL) is an electric power device which limits the fault current immediately in a power grid. The SFCL must be cooled to below the critical temperature of HTS(High Temperature Superconductor) modules. In general, they are submerged in sub-cooled liquid nitrogen for their stable thermal characteristics of HTS modules. To cool and maintain the target...

  4. 72. Progress in Development of a 10 kW Brayton Cryocooler for HTS Cable in Korea
    Ho-Myung Chang (Hong Ik University)
    29/06/2015, 09:00
    CEC-09 - Cryogenics for Power Applications, Energy, Fuels and Transportation
    Poster Presentation
    Recent progress in the development of a 10 kW Brayton cryocooler is presented for HTS cable systems under installation in Jeju Island, Korea. The role of this cryocooler is to continuously cool a liquid-nitrogen flow from 78 K to 67 K, and the liquid is pumped to three-phase 154 kV cable over a length of 1 km. The refrigerant of cryocooler is helium, whose operating pressure and flow rate was...

  5. 389. THE SAFE REMOVAL OF FROZEN AIR FROM THE ANNULUS OF AN LH2 STORAGE TANK
    Angela Krenn (NASA)
    29/06/2015, 09:00
    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Poster Presentation
    Large Liquid Hydrogen (LH2) storage tanks are vital infrastructure for NASA. Eventually, air may leak into the evacuated and perlite filled annular region of these tanks. Although the vacuum level is monitored in this region, the extremely cold temperature causes all but the helium and neon constituents of air to freeze. A small, often unnoticeable pressure rise is the result. As the leak...
