The pinnacle achievement of particle accelerators came in 2012, when the Large Hadron Collider (LHC) uncovered the long-sought Higgs boson particle. To solve these riddles, we will likely need a particle collider more powerful than those we have today. The Particle ZooThe story of particle accelerators began in 1897 at the Cavendish physics laboratory at the University of Cambridge. Because of the separation of the plasma electrons from the plasma ions, there is an electric field inside this wake. The main advantage of a plasma accelerator over other schemes is that electric fields in a plasma wake can easily be 1,000 times stronger than those in traditional radio-frequency cavities.
