<p>392 <a href="page.php?w=quadrupole_magnet">quadrupole magnet</a>s are used to keep the beams focused, with stronger quadrupole magnets close to the intersection points in order to maximize the chances of interaction where the two beams cross. Magnets of <a href="page.php?w=Multipole_expansion">higher multipole orders</a> are used to correct smaller imperfections in the field geometry. In total, about 10,000 <a href="page.php?w=superconducting_magnet">superconducting magnet</a>s are installed, with each of the 1232 dipole magnets having a mass</p><p>
