    This paper describes the development of 2 kW class reverse-Brayton refrigeration system. The refrigeration cycle is designed to have cooling capacity of 2 kW at 77 K, with operating pressure of 0.5 and 1.0 MPa at low and high pressure side. Neon gas is adopted as a working fluid. The system is consist of scroll compressor package, plate heat exchangers and turbo expander. Especially, several...

    ABSTRACT: An 18 kW@4.5 K & 4 kW@2 K helium refrigerator is being developed in China by the Technical Institute of Physics and Chemistry, CAS. This large-scale helium refrigerator provides different cooling capacity at the 50-75 K, 4.5-75 K and 2 K levels. This helium refrigerator works based on Claude cycle refrigeration process, which uses 5 sets of turbines (10 turbines totally) to bring the...

  3. 165. C3Po1B-05: Study of operational modes of cool-down and warm-up processes for the ESS large-scale 20 K helium refrigeration system
    Dr Hideki Tatsumoto (European Spallation Source)

    Poster

    At the ESS target, high energy spallation neutrons are produced by impinging 5 MW proton beam on the high-Z material, tungsten. The proton beam is pulsed with a repetition of 14 Hz and a pulse length of 2.86 ms. The spallation neutrons are moderated to cold and thermal energies by the moderators. The moderator system consists of a thermal water pre-moderator and two liquid hydrogen cold...

    Poster

    The National Synchrotron Light Source-II is an electron storage ring with a circumference of 792 m located at Brookhaven National Laboratory (BNL) in Upton, N.Y. The fourth-generation light source with an electron beam of 3 GeV using current up to 500 mA will be able to produce high intensity X-ray radiation and high-intensity infrared, as well as visible and ultraviolet light. The storage...

    Poster

    The Proton Improvement Plan-II (PIP-II) is a crucial upgrade to the Fermilab accelerator complex, featuring a new 800-MeV Superconducting Radio-Frequency (SRF) linear accelerator (LINAC) with 23 cryomodules operating at 2K. The LINAC thermohydraulic conditions are satisfied by the cryogenic subsystems: Cryogenic Distribution System (CDS), a helium refrigerator cold box (CB), a warm compression...
