Successful Magnet Test Puts LHC on Track for Upgrade
The U.S. LHC Accelerator Research Program (LARP) has successfully tested a powerful superconducting quadrupole magnet that will play a key role in developing a new beam focusing system for CERN’s Large Hadron Collider (LHC). This advanced system, together with other major upgrades to be implemented over the next decade, will allow the LHC to produce 10 times more high-energy collisions than originally planned.
Dubbed HQ02a, the latest in LARP’s series of High-Field Quadrupole magnets is wound with cables of the brittle but high-performance superconductor niobium tin (Nb3Sn). Compared to the final-focus quadrupoles presently in place at the LHC, which are made with niobium titanium, HQ02a has a larger aperture and superconducting coils designed to operate at a higher magnetic field. In a recent test at the Fermi National Accelerator Laboratory (Fermilab), HQ02a achieved all its challenging objectives.
