6 FAQs about [Energy storage magnetic ring parameters]

What is a storage ring light source?

Modern storage ring light sources have been very successful in providing high-flux, high-brightness, highly stable photon beams for many scientific applications. Their success is underpinned by sophisticated lattice designs that allow small emittance electron beams to be reached with a large complement of straight sections for insertion devices.

Why are diffraction-limited storage rings so popular?

Their success is underpinned by sophisticated lattice designs that allow small emittance electron beams to be reached with a large complement of straight sections for insertion devices. The design of such lattices is in continuous evolution, with the most modern trends aiming at diffraction-limited storage rings.

What is the vertical emittance of a storage ring?

In practice, the vertical emittance is dominated by magnet alignment errors. Storage rings typically operate with a vertical emittance that is of order 1% of the horizontal emittance, but many can achieve emittance ratios somewhat smaller than this. ∗T. Raubenheimer, SLAC Report 387, p.19 (1991).

What is the emittance ratio of a storage ring?

Storage rings typically operate with a vertical emittance that is of order 1% of the horizontal emittance, but many can achieve emittance ratios somewhat smaller than this. ∗T. Raubenheimer, SLAC Report 387, p.19 (1991). Quantum effects excite longitudinal emittance as well as transverse emittance.

How much photon energy can a storage ring reach?

The photon energy reach depends on the energy of the electron beam and therefore on the size of the storage ring. However, progress with undulator technology has allowed medium-energy machines (e.g., 3 GeV) to reach a brilliance in excess of 10 20 ph/s/0.1%BW/mm 2 /mrad 2 over a photon energy range extending beyond 10 keV.

Which ring should maintain a stable electron beam?

To satisfy them, storage ring should maintain a stable electron beam. Due to the ultralow emittance and strong magnet fields of 4GSR, stability tolerances of the storage ring and beamline is tighter than the tolerances of 3GSR.
