A particle accelerator is a machine that uses electromagnetic fields to propel ions to very high speeds and energies to contain them in well-defined beams. Small accelerators are used for fundamental

…RHIC had its last collisions and ended data collection on 6 February 2026. RHIC is an intersecting storage ring particle accelerator. Two independent rings (arbitrarily denoted as "Blue" and "Yellow") circulate heavy ions and/or polarized protons in opposite directions and allow a…
The Tevatron (background circle), a synchrotron collider type particle accelerator at Fermi National Accelerator Laboratory (Fermilab), Batavia, Illinois, USA. Shut down in 2011, it was the most powerful particle accelerator in the world until 2007, accelerating protons to an energy of over 1 TeV (tera electron volts). Beams of protons and antiprotons, circulating in opposite directions in the rear ring, collided at two magnetically induced intersection points.
