What is big particle accelerator on the French-Swiss border, restarted in 2009 after extensive repairs?
Particle accelerator energy particle accelerator used for elementary particle physics is the Large Hadron Collider (LHC) at CERN, operating since 2009. Nuclear physicists and cosmologists may use beams of bare atomic nuclei, stripped of electrons, to investigate the structure, interactions, and properties of the nuclei themselves, and of condensed matter at extremely high temperatures and densities, such as might have occurred in the first moments of the Big Bang. These investigations often involve collisions of heavy nucleiof atoms like iron or goldat energies of several GeV per nucleon. The largest such particle accelerator is the Relativistic Heavy Ion Collider (RHIC) at Brookhaven
Particle accelerator as aspect ratio, current intensity, and position on target, communicates with and assists accelerator maintenance personnel to ensure readiness of support systems, such as vacuum, magnet power supplies and controls, low conductivity water (LCW) cooling, and radiofrequency power supplies and controls. Additionally, the accelerator operator maintains a record of accelerator related events. Particle accelerator A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams. Large accelerators are used for basic research in particle physics. The most powerful accelerator currently is the Large Hadron
