In detectors, light guides like this one are used to carry signals to the electronics for recording.
The 3.70 metre Big European Bubble Chamber (BEBC) was dismantled on 9 August 1984. One of the biggest detectors in the world, it produced direct visual recording of particle tracks. 6.3 million photos of interactions were taken with the chamber in the course of its existence.
The first ever circular particle accelerator, a cyclotron, was just a few centimetres in diameter. Invented in 1930 by Ernest Lawrence, it was the fore-runner of today's huge machines.
Antiproton target used for the AA (antiproton accumulator). Making an antiproton beam took a lot of time and effort. Firstly, protons were accelerated to an energy of 26 GeV in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 - three hundred thousand million - antiprotons.
