Engineering model used for the construction of the OPAL detector at the LEP accelerator.Scale=1/10
3 bubble chamber film rolls from the 2m bubble chamber.
Model of the LEP tunnel as it is in the 1990's. LEP(Large Electron Positron collider) was the world biggest accelerator.
Wire chamber
This focusing horn was developed in 1992 by Remo Maccaferri, Jean Claude Schnuriger and Lubrano di Scampamorte and is still operating in the AD complex at CERN (as of 2017). This device could pulse at 400 KA (160 KA for the previous version). This enabled an antiproton collection ten times better than the old one. Firstly, protons were accelerated to an energy of 26 GeV/c and ejected onto a metal target. From the spray of emerging particles, the 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, ten antiprotons were captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 - three hundred thousand million - antiprotons. Originally magnetic focusing horns were developed by Simon van der Meer - see for example object AC-022 in this database.

30cm diameter hydrogen bubble chamber for the SC (synchro-cyclotron)
Used to mesure the magnetic field.
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.
