Storage ring
![The 216 m circumference storage ring dominates this image of the interior of the Australian Synchrotron facility. In the middle of the storage ring is the booster ring and linac](/Images/godic/202502/13/Aust.-Synchrotron-Interior-Panorama,-14.06.20071452.jpg")
![Different types of magnets used in the storage ring of the Australian Synchrotron. The larger yellow one is a dipole magnet used to bend the electron beam and produce the synchrotron radiation. The green one is a sextupole magnet and the red one (behind the dipole) is a quadrupole magnet which are used for focusing and to maintain chromaticity respectively.](/Images/godic/202502/13/Aust.-Synchrotron,-Storage-Ring-Magnets,-14.06.20071452.jpg")
A storage ring is a type of circular particle accelerator in which a continuous or pulsed particle beam may be kept circulating typically for many hours. Storage of a particular particle depends upon the mass, momentum and usually the charge of the particle to be stored. Storage rings most commonly store electrons, positrons, or protons.
