Proton Synchrotron, Particle accelerator at CERN research complex, Geneva, Switzerland
The Proton Synchrotron is a particle accelerator at CERN's research complex in Geneva that speeds up protons and heavy ions in a circular tunnel stretching around 628 meters. The machine uses 277 electromagnets arranged in precise positions to direct and prepare particles for scientific experiments.
The facility began operating in 1959 and was briefly the most powerful particle accelerator in the world at that time. It marked a turning point in the development of high-energy physics experiments in Europe.
This facility represents a symbol of European scientific cooperation, showing how researchers from different nations gather to conduct experiments together. Visitors can see firsthand how international science works and the role this center plays in the global research landscape.
The machine works with various particle types and can handle proton beams at much higher intensities than in earlier years. Visitors should know that tours of the site are available but typically require advance booking and adherence to safety protocols.
The device kept its original 1959 structure but was fitted with modern control systems that make particle beams a thousand times more intense. This shows how research equipment can be kept operational for decades through continuous technological improvements.
