An Advance in Superconducting Magnet Technology Opens the Door for More Powerful Colliders

(PhysOrg.com) -- Preparing for as much as a 10-fold increase in the Large Hadron Collider's luminosity within the next decade, U.S. scientists and engineers have demonstrated a powerful magnet based on an advanced superconducting material, which can produce magnetic fields strong enough to focus intense proton beams in the LHC's upgraded interaction regions.

The superconducting inner triplet magnets now in place at the LHC operate at the limits of well-established niobium-titanium (NbTi) magnet technology. One of the LARP goals is to develop upgraded magnets using a different superconducting material, niobium tin (Nb3Sn). Niobium tin is superconducting at a higher temperature than niobium titanium and therefore has a greater tolerance for heat; it can also be superconducting at a magnetic field more than twice as strong.
Unlike niobium titanium, however, niobium tin is brittle and sensitive to pressure; to become a superconductor when cold it must be reacted at very high temperatures, 650 to 700 degrees Celsius. Advanced magnet design and fabrication methods are needed to meet these challenges
