Rebooting the world’s largest particle accelerator—daunting doesn’t come close


Scientists say they will need at least four months to reopen the world’s biggest particle physics laboratory after the coronavirus crisis forced CERN to move nearly all 8,000 staff off-site. While that’s already a huge undertaking, it pales in comparison with the colossal task of restarting CERN’s gigantic complex of particle accelerators, which includes the atom-smashing Large Hadron Collider. Frédérick Bordry, director for Accelerators and Technology and part of CERN’s crisis team, explains the work behind this complex process.
