Accelerator physics: In the wake of success

Robert Bingham1

Particle accelerators tend to be large and expensive. But an alternative technology, which could result in more compact, cheaper machines, is proving its viability for the acceleration of subatomic particles.

Since the construction of the first particle accelerator in 1932, high-energy collisions of accelerated ions or subatomic particles (such as electrons and their antimatter counterpart, positrons) have proved a useful tool in physics research. But the escalating size and cost of future machines means that new, more compact acceleration techniques are being sought.
