A simulated particle collision in the LHC. The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.
CERN has several preliminary designs for a Future Circular Collider (FCC)—which would be the most powerful particle accelerator ever built—with different types of collider ranging in cost from around €9 billion (US$10.2 billion) to €21 billion. It would use the LHC ring as preaccelerator, similar to how the LHC uses the smaller Super ...
Fermitron was an accelerator sketched by Enrico Fermi on a notepad in the 1940s proposing an accelerator in stable orbit around the Earth. The undulator radiation collider [7] is a design for an accelerator with a center-of-mass energy around the GUT scale. It would be light-weeks across and require the construction of a Dyson swarm around the Sun.
The Large Hadron Collider at CERN with its High Luminosity upgrade is the world's largest and most powerful particle accelerator and is expected to operate until 2036. A number of different proposals for a post-LHC research infrastructure in particle physics have been launched, including both linear and circular machines.
The baseline design of the LHeC consists in two superconducting linear particle accelerators ("linacs") each about 1 km long, arranged in a racetrack configuration tangential to the LHC. Each linac provides about 10 GV acceleration, therefore the electrons makes three turns in the racetrack reaching an energy of about 60 GeV before colliding ...
Anatoli Petrovich Bugorski (Russian: Анатолий Петрович Бугорский; born 25 June 1942) is a Russian retired particle physicist. He is known for surviving a radiation accident in 1978, when a high-energy proton beam from a particle accelerator passed through his head.
The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed. It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, Switzerland. LEP collided electrons with positrons at energies that reached 209 GeV.
The first cyclotron, an early type of particle accelerator, was built by Ernest O. Lawrence in 1931, with a radius of just a few centimetres and a particle energy of 1 megaelectronvolt (MeV). Since then, accelerators have grown enormously in the quest to produce new particles of greater and greater mass.
