C1Po2D: Large Scale IV: Cryogenic Test Facility Design
- Romain Bruce (Fermilab)
- Robert Duckworth (Oak Ridge National Laboratory)
The High Luminosity (HL-LHC) upgrade of the Large Hadron Collider at CERN is an example of large-scale international scientific cooperation which spans multiple international partners. Canada through TRIUMF is making an in-kind contribution to the project with the delivery of 5 crab cavity cryomodules. The cryomodules will be delivered to CERN by 2026 for installation in the LHC. TRIUMF will...
PIP-II HB650 SRF cavities have a very ambitious performance specifications of achieving a Q factor of 3e+10. Each cavity must undergo vertical tests and demonstrate its performance before it can be qualified for assembly into a cryomodule. The vertical tests are conducted at 2 K, in very low residual magnetic field less than 0.5 uT. In order to expel magnetic field trapped inside the cavity it...
The HFVMTF (High Field Vertical Magnet Test Facility) is a new experimental facility under development at Fermi National Accelerator Laboratory (FNAL) to test large superconducting magnets (up to 20 tons weight and 1.3 m diameter) in a double bath superfluid helium cryostat (1.9 K and 1.2 bar). Coupled with a superconducting dipole magnet fabricated by Lawrence Berkeley National Laboratory...
A new 20,000 liter (20 KL) liquid helium dewar is being integrated in to the existing cryogenic system at the Facility for Rare Isotope Beams at Michigan State University (MSU-FRIB). This dewar will serve a new planned cold box system that supports the large experimental system superconducting magnets and the many legacy superconducting magnets in the downstream beamline. This dewar has a...
A design for a 4.2 K cryostat to support superconducting undulator (SCU) magnets is being developed as part of an SCU free electron laser (FEL) technology demonstrator. An array of several cryostats will be installed as an afterburner at the end of the existing hard x-ray beam line of the LCLS-II facility at the SLAC National Accelerator Laboratory (SLAC). Cryostat requirements include high...
