CERN Superconducting Cables Connection Cryostats (Cold Boxes)

Coordinating university: Uppsala University, www.uu.se

Project description
The High Luminosity Large Hadron Collider (HL-LHC) at CERN is an upgrade of the LHC to achieve instantaneous luminosities a factor of five larger than the LHC nominal value. More powerful superconducting magnets are needed and their powering relies on essential and critical connections between MgB2 cable and a high temperature superconductor current lead. These connections need to be cooled by cryogens and must be able to carry an unprecedented current capacity of up to 100 kA each. The devices where these connections are made have to be cryogenic and high current compatible as well as compact.
