  1. 406. Testing of Full-Scale Prototype Cryoviscous Compressor at SNS for ITER Vacuum System
    Robert Duckworth (Oak Ridge National Laboratory)

    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Contributed Oral Presentation
    To pump the ITER torus exhaust gas from the regenerating torus cryopumps, which will be a mixture of deuterium, tritium, and helium with trace impurities, a prototype cryoviscous compressor (CVC) has been designed, fabricated, and is under test. This prototype, which was based on success ful demonstration of a sub-scale version, consists of a set of 24 5-cm diameter, 1.27-m long stainless...

    CEC-05 - Expanders, Pumps, Compressors, and Regenerators
    Contributed Oral Presentation
    In the past, cooling at 2K used to be an exotic application in large scale cryogenics. The required sub-atmospheric helium bath was established with the help of one of the following two technical approaches – rough vacuum pumping at ambient temperature or turbo compression at cryogenic temperature – or a combination of both. The aforementioned approaches are still being applied, but the...

  3. 320. Adaptation of refrigeration compressors for Joule-Thomson cryocoolers fed with gas mixtures
    Dr Agnieszka Piotrowska (Wroclaw University of Technology)
    29/06/2015, 11:30
    CEC-03 - Cryocoolers (Non-Aerospace)
    Contributed Oral Presentation
    Closed cycle Joule-Thomson (J-T) refrigerators supplied with gas mixtures are perspective coolers in many applications requiring low-cost and reliable sources of cooling power below 100 K. They are characterized by relatively simple construction and lack of moving parts working at low temperatures. The refrigerants are composed of nitrogen and hydrocarbons. Working pressure can as low as about...

  4. 33. Development of an oil-free compressor for GM and pulse tube cryocoolers
    Dr Jens Höhne (Pressure Wave Systems GmbH)
    29/06/2015, 11:45
    CEC-05 - Expanders, Pumps, Compressors, and Regenerators
    Contributed Oral Presentation
    Pressure Wave Systems GmbH has developed an oil-free compressor for GM and pulse tube cryocoolers. The concept is based on hydraulically driven metall bellows which compress the Helium working gas. The system has 1kW of electrical input power and has been successfully tested with a SHI SRDK-101D GM cryocooler cold head. Set-up, performance and reliability of the compressor system will be discussed.

  5. 207. Engineering, Manufacture and Preliminary Testing of the ITER Toroidal Field (TF) Magnet Helium Cold Circulator
    Mr Chris Rista, P.E. (Barber-Nichols Inc.)
    29/06/2015, 12:00
    CEC-05 - Expanders, Pumps, Compressors, and Regenerators
    Contributed Oral Presentation
    The ITER cryodistribution system provides the supercritical Helium (SHe) forced flow cooling to the magnet system using cold circulators. The cold circulators are located in each of five separate auxiliary cold boxes planned for use in the facility. Barber-Nichols Inc. has been awarded a contract from ITER-India for engineering, manufacture and testing of the Toroidal Field (TF) Magnet Helium...
