Accelerators and storage rings are coupled physical systems designed to generate, manipulate, and store high-energy charged particle beams under precisely controlled electromagnetic fields. Accelerators, such as linear accelerators or synchrotrons, use radiofrequency cavities and magnet lattices (dipoles, quadrupoles, higher multipoles) to incrementally increase beam energy and control transverse and longitudinal dynamics. Storage rings maintain beams on closed orbits for extended durations, employing sophisticated lattice designs, beam optics, and feedback systems to preserve emittance, energy spread, and stability while enabling collisions or extraction for experiments, synchrotron radiation production, or secondary beam generation.
While synchrotron radiation is often thought of as "stable," the electromagnetic field exhibits pronounced randomly fluctuating distributions both temporally and spatially. These fluctuations encode spatial information about ...
