Storage ring
Encyclopedia : S : ST : STO : Storage ring
A storage ring consists of a circular ring in which a particle beam or charged particles on a beamline from a particle accelerator can be kept circulating almost indefinitely. Storage of a particular particle is based on the mass of the particle being stored. There are some particles that are heavier than others requiring more energy for storage.
A storage ring is a type of synchrotron.
Criteria for Storage of a particle beam
Most common conditions for storage of a particle beam are:
Magnets
High current, low voltage Focusing magnets and/or bending magnets must be standardized by premapping parameters of the magnet/magnetic fields, using computer algorithms for position, and focusing achromats. For a synchrotron, the magnets are sequenced according to the Chasman-Green lattice.
Vacuum
A better vacuum yields better beam diagnostics.
Timing
The timing of the release of the beam and the storage duration are important.
Typically there are pulsed magnets in a storage ring to kick a beam into the ring (called Injection kicker magnets) and to kick a beam out of the ring (called Extraction kicker magnets). These magnets are driven by a high voltage modulator to produce magnetic fields with very fast rise and fall times. The junction in a storage ring where the beampipe sections off or comes in is called the septum; hence, there are two septums in one storage ring.
An accumulator ring is slightly different from a storage ring.
