  1. 9. The liquid nitrogen system for chamber A: a change from forced flow to a natural flow (thermo siphon) system
    Dr Ahmed Sidi-Yekhlef (Jefferson Laboratory), Mr Jonathan Homan (NASA-Johnson Space Center)
    25/09/2008, 09:00
    OPERATION
    NASA at the Johnson Space Center (JSC) in Houston is presently working toward modifying the original forced flow liquid nitrogen cooling system for the thermal shield in the environmental control chamber-A (65’ dia x 120’ high) to work as a natural flow (thermo siphon) system. The new thermo siphon system will improve the reliability, stability, and operating temperature while reducing the...

  2. 18. Helium liquefaction and distribution at TIFR, Mumbai, INDIA
    Mr K V Srinivasan (Tata Institute of Fundamental Research)
    25/09/2008, 09:30
    OPERATION
    The low temperature facility (LTF) of Tata Institute of Fundamental Research, (TIFR) Mumbai, India, has been operating and maintaining helium liquefiers and nitrogen generators for more than four decades. For the past sixteen years, helium is liquefied in KOCH’s model 1610S helium liquefier (production during 2007: 60000 ltrs). A new helium liquefier (Linde L280) has been recently...

  3. 20. Design status of the cryogenic system of JT60-SA: optimization of the refrigeration capacity for different operation modes
    Dr Christine HOA (CEA Grenoble)
    25/09/2008, 10:30
    OPERATION
    The JT-60SA project is a combined project of the Japanese and European Satellite Tokamak Programme under the Broader Approach Programme. The tokamak will be operated in 2015 in Japan and will support ITER exploitation and research towards DEMO. This tokamak is currently in the conception design phase. The cryogenic system of JT60-SA is designed to provide supercritical helium at 4.5 K, to...

  4. 22. Collection of data related to the operation experience on the Tore Supra cryogenic system
    Mr Pascal reynaud (CEA Cadarache)
    25/09/2008, 11:00
    OPERATION
    Operating modes of the cryoplant are reconstructed for the considered years, thus allowing a more precise calculation of the system availability relatively to its exploitation period and to the plasma exploitation period. Operating times, number and type of failures, failure rates and mean time between failures are given for the main components of the system. The study focuses on the years...

  5. 34. Focus of Jefferson Laboratory’s Collins Cryogenic Institute Research and Development
    Mr Dana Arenius (Jefferson Laboratory)
    25/09/2008, 11:30
    OPERATION
    Recognized as a key core laboratory technology, Jefferson Lab established the Collins Cryogenic Institute in 2006 to complement its other research areas inclusive of SRF technology. Combining graduate engineering degree thesis work with applied research and development of helium refrigeration technology, the Institute’s focus areas include improved process cycles, higher system...
