All the particles used in experiments at CERN go through the PS, are accelerated to the speed of light, and fed to other machines in the complex. The PS is the oldest of CERN's accelerators, and has been running continuously since 1959.
Particles coming from the linear accelerator have a relatively low speed.
The ring, made of a vacuum pipe surrounded by magnets, measures 200 meters in diameter. CERN Like other circular accelerators, the PS requires dipole magnets to bend the particle beam around the ring. But unlike magnets in other machines, the PS magnets are combined, and fulfill both functions. A device in the machine called the RF cavity is where the acceleration takes place. The cavity can store electric energy, which it transfers to a passing particle.
