The Large Hadron Collider recently got back to work after a two-year layoff for maintenance and upgrades, but soon it will go under the knife again. Last week 230 scientists met at CERN in Switzerland to discuss the High-Luminosity LHC (HL-LHC) project, and move it from the development phase to the construction stage. After two more Long Shutdown periods in 2019 and 2024, the HL-LHC will deliver 10 times the amount of particle collisions it does now. New technology coming its way includes 12 superconducting quadropole magnets (one is pictured above), "crab" cavities that tilt the particle beams before collisions and more. When we took a look at the science behind particle accelerators a few years ago, the HL-LHC was already in development and after a four year design study it's one (big) step closer to reality.
