Cosmotron

The Cosmotron was a particle accelerator, specifically a synchrotron, that was built at Brookhaven National Laboratory in the United States. It became operational in 1952 and was one of the first accelerators to achieve high-energy collisions of particles. The Cosmotron was designed to accelerate protons to energies of around 3 billion electron volts (3 GeV), which allowed physicists to explore fundamental questions about the constituents of matter and the forces governing their interactions.
