    Contributed Oral

    The High Rigidity Spectrometer (HRS) will be the centerpiece experimental tool of the Facility for Rare Isotope Beams (FRIB) fast-beam program. The HRS project is staged in two phases: the High Transmission Beam Line (HTBL) phase followed by the Spectrometer (SPS) phase. The HTBL will contain 24 superconducting quadrupole magnets (in 8 triplet cryostats), four superconducting dipole magnets,...

    The Cryogenic Division at Fermilab is dedicated to designing and fabricating large cryogenic facilities for particle accelerators, as well as test facilities for superconducting magnets and cavities. The development of these large-scale facilities necessitates innovative numerical tools to aid in the design of various components and to provide more accurate estimates of heat loads. Several...

  3. 47. C2Or2C-03: Modelling two-phase He II flow for heat load limits in EuXFEL cryomodules for CW operation
    Dr Aman Kumar Dhillon (Deutsches Elektronen-Synchrotron DESY)

    Contributed Oral

    The European XFEL is under consideration for a High Duty Cycle (HDC) upgrade to enable Continuous Wave (CW) or Long Pulse (LP) operation, enhancing the user’s operational range. One of the key challenges for this upgrade is managing the increased heat load of the existing cryomodules while ensuring sufficient cryogenic capacity for stable operation. The two-phase pipe within the cryomodules...

    Contributed Oral

    CEA Grenoble DSBT (Low Temperature System Department) commissioned in 2004 a test facility with a cooling capacity of 400W@1.8K (or 800W@4.5K). This system comprises a cold box with two centrifugal cold compressors, a cold turbine, a wet piston expander, counter flow heat exchangers and a phase separator at 4.5 K and a large Multi-Test Cryostat than can include a phase separator at 1.8 K. It...

  5. 136. C2Or2C-05: Development of a simulation code for analyzing pressure and temperature fluctuations in the J-PARC cryogenic moderator system
    Dr Hideki Tatsumoto (European Spallation Source ERIC (ESS))

    Contributed Oral

    At the Japan Proton Accelerator Research Complex (J-PARC), three hydrogen moderators operate using supercritical hydrogen at 1.5 MPa and 18 K. Nuclear heating induced in the hydrogen moderator during 1-MW proton beam operation is estimated to be 3.8 kW. A cryogenic moderator system (CMS) was designed to circulate the supercritical hydrogen at 162 g/s, effectively removing this transient heat...
