ACCELERATORS Introduction Particle accelerators are used to study matter and energy. They accelerate charged particles through an electric field in an evacuated tube. The particles collide into a target or another particle. The collision point is in a detector, which records how the particles collide. All accelerators use a strong magnetic field to move particles. They all have the same three main parts: * A source of particles or ions * A tube pumped to a vacuum * A way of speeding up the particles. The three main types are: * cyclotron (spiral) * synchrotron (circular) * linear (linac) Cyclotron A cyclotron is a resonance accelerator. It has of two large dipole magnets which produce a semi-circular region of magnetic field. An oscillating voltage is applied to produce an electric field across the gap between the 2 semicircles. Particles are injected into the magnetic field region. They go in a semicircular path until they reach the gap. Then the...
