A synchrotron radiation (SR) facility typically consists of an injector, a storage ring, and SR beamlines. The latter two features are unique to SR facilities, when compared to other types of accelerator facilities. The SR facilities have the characteristics of low injection beam power, but high stored beam power. The storage ring is generally above ground with people occupying the experimental...

This issue marks the 50th anniversary of the first observation of synchrotron radiation light from the General Electric 70 MeV synchrotron and coincides with the third anniversary of the Journal of Synchrotron Radiation (JSR). The issue brings together review articles from some of the pioneers of the field and in our view forms a unique historical record. The interdisciplinary nature of synchro...

Synchrotron radiation imaging with refraction enhancement was successfully applied to image air voids in opaque plastic materials, which otherwise could hardly be depicted(1). It was suggested that this imaging technique had a superior performance in nondestructive testing of small voids in plastics(1). It has been recognised in previous works that the edge enhancement effect due to X-ray refra...

Emission of light by a single electron moving on a curved trajectory (synchrotron radiation) is one of the most well-known fundamental radiation phenomena. However experimental situations are more complex as they involve many electrons, each being exposed to the radiation of its neighbors. This interaction has dramatic consequences, one of the most spectacular being the spontaneous formation of...

We calculate the spectral energy distribution (SED) of electromagnetic radiation and the spectrum of high energy neutrinos from BL Lac objects in the context of the Synchrotron Proton Blazar Model. In this model, the high energy hump of the SED is due to accelerated protons, while most of the low energy hump is due to synchrotron radiation by co-accelerated electrons. To accelerate protons to s...

Associated with the experimental discoveries of Čerenkov radiation and synchrotron radiation, separate theoretical analyses were based on the different physical circumstances of the two phenomena. In recent years, Erber and collaborators have noted in a series of papers5−13 that when a relativistic charged particle traverses a dielectric medium subject to an applied magnetic field the resulting...

These notes represent an introduction to the physics of synchrotron radiation. Such radiation is produced by relativistic electron beams being de‡ected by magnetic ...eld. Speci...cally, relativistic electron beams are injected into circular accelerators, called storage rings, where they circulate for many hours while continuously producing synchrotron radiation for the bene...t of research in ...

Pushing to higher light-source performance will eventually require using linacs rather than storage rings, much like colliding-beam storage rings are now giving way to linear colliders. r 2003 Elsevier Science B.V. All rights reserved. PACS: 07.85.Qe; 07.85. m Synchrotron radiation sources have proven to be immensely important tools throughout the sciences and engineering. In consequence, synch...
