  1. 418. ARIEL E-linac Cryogenic System: Commissioning and First Operational Experience
    Alexey Koveshnikov (TRIUMF)

    CEC-02 - Large-Scale Systems, Facilities, and Testing
    Contributed Oral Presentation
    The Advanced Rare IsotopE Laboratory (ARIEL) is a major expansion of the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. A key part of the ARIEL project is a 10 mA 50 MeV continuous-wave superconducting radiofrequency (SRF) electron linear accelerator (e-linac). The 1.3 GHz SRF cavities are operated at 2 K. HELIAL LL helium liquefier by Air Liquide Advanced Technologies (ALAT)...

    CEC-01 - Large-Scale Refrigeration and Liquefaction
    Contributed Oral Presentation
    The new 4.5 K refrigerator system at the Jefferson Lab (JLab) Central Helium Liquefier (CHL-2) for the 12 GeV upgrade was commissioned in late spring of 2013, following the commissioning of the new compressor system, and has been supporting 12 GeV LINAC commissioning since that time. The six design modes were tested during commissioning, consisting of a maximum capacity condition, nominal...

  3. 284. Commissioning and Operational Results of the 12 GeV Helium Compression System at JLab
    Mr Peter Knudsen (Jefferson Lab)
    01/07/2015, 11:30
    CEC-01 - Large-Scale Refrigeration and Liquefaction
    Contributed Oral Presentation
    The new compressor system at Jefferson Lab (JLab) for the 12 GeV upgrade was commissioned in the spring of 2013 and incorporates many design changes, discussed in previous publications, to improve the efficiency, reliability and maintainability as compared to previous compressor skids used for this application. The 12 GeV helium compression system has five compressors configured with four...

    CEC-01 - Large-Scale Refrigeration and Liquefaction
    Contributed Oral Presentation
    The helium cryogenic system at Spallation Neutron Source (SNS) provides cooling to 81 superconducting radio frequency cavities. During the first ten years of operation, much operational experience and lessons learned have been gained. The lessons learned include integrated system issues as well as component failures in the areas of mechanical, electrical and controls. Several single point...

  5. 294. 2K Pump Down Studies at SNS
    Matthew Howell (UT Battelle/ORNL)
    01/07/2015, 12:00
    CEC-01 - Large-Scale Refrigeration and Liquefaction
    Contributed Oral Presentation
    The Spallation Neutron Source (SNS) linear accelerator consists of 81 superconducting radio frequency (SCRF) cavities cooled to 2.1K by a cryogenic refrigeration system. The 2.1 K cold box consists of four stages of cold compressors with LN2 cooled variable speed motors. Transitioning from 4K operation to 2.1K operation in the cryomodules involves pumping the cryomodules down from...
