The cooling of the superconducting magnet cold masses with superfluid helium (HeII) is a well-established concept successfully in operation since years in the LHC. Consequently, its application for the cooling of FCC magnets is an obvious option. The 12-kW heat loads distributed over 10-km long sectors not only require an adaption of the magnet bayonet heat exchangers, but also present new...
The Future Circular Collider (FCC) under study at CERN will produce 50-TeV high-energy proton beams. The high-energy particle beams are bent by 16-T superconducting dipole magnets operating at 1.9 K and distributed over a circumference of 80 km. The circulating beams induce 5 MW of dynamic heat loads by several processes such as synchrotron radiation, resistive dissipation of beam image...
Both LCLS II 2K cold boxes feature a large vacuum vessel topped by a 2” thick flat plate, buttressed by a central column, that supports six cold compressors and connected piping. Multiple external bayonet arrangements permit modification of the flow path through the box so the nominal flow can be adjusted approximately 24% without altering the internal piping. All piping and the vacuum vessel...
Proton Improvement Plant – II (PIP-II) has been planned at Fermilab for providing powerful, high-intensity proton beams to the laboratory’s experiments. The heart of PIP-II is an 800 MeV Superconducting (SC) linear accelerator (Linac), which will provide 1.2 MW proton beam needed for the Long-Baseline Neutrino Facility (LBNF). The SC Linac accelerates the beam from 2.1 MeV to 0.8 GeV and...
The Accelerator of CIADS (China Initiative Accelerator Driven System) will be built in the nearly future at IMP in china. All the superconducting cavities will be running at 2K . So a helium cryogenic system has been designed according to the requirements of the CIADS Accelerator. The total heat load of the cryogenic system is about 4.2kW at 2K, 2.1kW at 4.5K and 7.5kW at 60K . And the total...
