The SM18 test facility, located in France, near the Meyrin site, was originally built to test and validate the magnets and radiofrequency (RF) cavities of LEP (the Large Electron–Positron Collider). It has since seen over 1700 such components pass through it – including, of course, those of the LHC – and is now preparing to welcome the magnets and RF cavities of the future HL-LHC, CERN Bulletin.
