Particle accelerator, a historic proton synchrotron, no longer in operation. Discovered the anti-proton as expected, followed by an unexpected plethora of resonances, "strange particles", hyperons, and other objects mostly observed in a large hydrogen bubble chamber, and feeding into the eventual development of the quark theory and "The Standard Model".

  • This accelerator was built in 1954 to accelerate protons to high enough energy to create anti-protons (ie, anti-matter protons, with negative charge), needing about 5 GeV energy for a stationary target. It had a large aperture (weak focusing beam optics) and thus an enormous iron magnet, weighing about 10,000 tons. The anti-proton was observed on schedule in 1995, resulting in Nobel prizes for Segre and Chamberlain in 1959. Shutdown in 1994, though the building remains in this image.
  • Ooops, the anti-proton was observed in 1955, I mistyped on the previous comment.
