List of accelerators in particle physics

Last updated

A list of particle accelerators used for particle physics experiments. Some early particle accelerators that more properly did nuclear physics, but existed prior to the separation of particle physics from that field, are also included. Although a modern accelerator complex usually has several stages of accelerators, only accelerators whose output has been used directly for experiments are listed.

Contents

Early accelerators

These all used single beams with fixed targets. They tended to have very briefly run, inexpensive, and unnamed experiments.

Fixed-target accelerators

More modern accelerators that were also run in fixed target mode; often, they will also have been run as colliders, or accelerated particles for use in subsequently built colliders.
