particle accelerators
– a machine capable of unlocking some of the fundamental secrets of nature itself.
– A modern particle accelerator consists of a series of specially shaped cavities surrounded by a metal (usually copper) through which an alternating voltage is passed. When this voltage is positive, the cavity attracts negatively charged particles (normally electrons), and draws them in; when it is negative, it repels and expels them. If the particles to be accelerated are positive (such as protons) the principle is the same but the voltages are the other way around.
synchrotron
– a particle accelerator that produces exceptionally bright X-rays which illuminate unseen worlds of atoms, molecules and fibres.
neutrinos
– ethereal particles which pervade the universe but rarely interact with anything while they are doing so
