Three pieces. Wire chambers used for the beams at CERN's Proton Synchrotron accelerator in the 1970s. Multi-wire detectors contain layers of positively and negatively charged wires enclosed in a chamber Multi-wire detectors contain layers of positively and negatively charged wires enclosed in a chamber full of gas. A charged particle passing through the chamber knocks negatively charged electrons out of atoms in the gas, leaving behind positive ions. The electrons are pulled towards the positively charged wires. They collide with other atoms on the way, producing an avalanche of electrons and ions. The movement of these electrons and ions induces an electric pulse in the wires which is collected by fast electronics. The size of the pulse is proportional to the energy loss of the original particle.

Swedenborg InstituteThe Intersecting Storage Rings (ISR) was the world's first hadron collider. It operated from 1971 to 1984 and held the record luminosity for hadron colliders till 2004. The ISR hosted the first superconducting quadrupole magnets. The ISR low-$\beta$ quadrupole magnets were part of a luminosity upgrade program. The coils were wound using a rectangular Cu/Nb-Ti wire, enamel insulated, and were epoxy impregnated. Glass-epoxy bands kept the coils together in the quadrupole configuration and withstood the electromagnetic forces.
The Large Electron-Positron Collider (LEP) was the largest lepton collider ever built, and gave high precision measurements of the W and Z particles. LEP was commissioned in 1989 and shut down in 2000, to leave room for the LHC. In conjunction with an energy upgrade, new, superconducting, final- focus (low-$\beta$) quadrupole magnets were built. The new magnets resembled much those built for the ISR luminosity upgrade, i.e., the coils were wound with a single rectangular wire. They operated at 4.5 K in a cryostat especially developed to fit into the limited space available in the shield placed in front of the experiment.
