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,...
Super Fragment Separator (SFRS), currently under construction at FAIR GmbH, is a superconducting powerful in-flight facility which will provide spatially separated isotopic beams up to elements of the heaviest projectiles. The facility is divided into 8 functional sections, called branches, and ultimately will comprise 63 cryostats containing dipole and multiplet magnets. The magnets in the...
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...
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...
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...
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...
