Arriving at CERN from Novosibirsk’s Budker Institute are magnets for the two transfer lines to feed the LHC collider with protons from the SPS proton synchrotron.
Some 360, 6 m dipoles and 180, 1.4 m quadrupoles will be installed in two new underground transfer tunnels, each about 3 km long, linking the SPS and LHC/LEP tunnels. One tunnel is being built by the Swiss as part of its host state contribution for the LHC.
To equip the tunnels, 10 magnet consignments per month will cover the 6000 km from Siberia over the next 18 months, each bearing two dipoles and a quadrupole.
Unlike the LHC’s main magnets, these are not superconducting. The Budker Institute supplies them under the 1993 Co-operation Agreement, which covers Russian participation in the LHC.
Preliminary work for dipole elements is handled by the Efremov Institute, St Petersburg, and for quadrupoles by the ZVI factory in Moscow. Additional manufacture and final assembly for the magnets is done at Novosibirsk.
