The power of attraction: Magnets in particle accelerators

In 1820, Hans Christian Oersted gave a demonstration on electricity to a class of advanced students at the University of Copenhagen in Denmark. Using an early battery prototype, he looked to see what effect an electric current ...

Scientists create the first diamond X-ray micro lens

After fourth-generation synchrotrons were invented (these are particle accelerators, which are, in fact, giant research facilities), there was an urgent need for a fundamentally new optics that could withstand high temperatures ...

Colliding molecules and antiparticles

Antiparticles—subatomic particles that have exactly opposite properties to those that make up everyday matter—may seem like a concept out of science fiction, but they are real, and the study of matter-antimatter interactions ...

Fusion by strong lasers

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires ...

Cooking up a new theory for better accelerators

While particle accelerators may be on the cutting edge of science, the building and preparation of some particle accelerator components has long been more of an art form, dependent on recipes born of trial and error. Now, ...

Particle accelerator

A particle accelerator (or atom smasher) is a device that uses electric fields to propel electrically-charged particles to high speeds and to contain them in well-defined beams. An ordinary CRT television set is a simple form of accelerator. There are two basic types: linear accelerators and circular accelerators.

This page describes types of particle accelerators. For a list of existing and historic particle accelerators see: List of accelerators in particle physics.
