Progress Toward an Ultimate Storage Ring Light Source

Progress toward an ultimate proof of the prion hypothesis.

E indications that the infectious agent responsible for scrapie did not contain nucleic acid (1) led to several insightful hypotheses to explain this conundrum (2). Eventually considerable data came to support one of these ideas, dubbed the prion hypothesis, also shown to be applicable to related fatal transmissible spongiform encephalopathies including Creutzfeldt–Jakob and mad cow disease (3)...

Designing an Ultra Low Emittance Lattices for Iranian Light Source Facility Storage Ring

Electron storage rings are extensively used for high luminosity colliders, damping rings in high-energy physics and synchrotron light sources. To further increase the luminosity at the colliders or brightness of a synchrotron light sources, the beam emittance is being continually pushed downward. In this paper, we investigate the lattice design for the storage ring of Iranian Light Source Facil...

An X-ray Free Electron Laser Driven by an Ultimate Storage Ring*

There is a worldwide interest in developing so-called ultimate storage ring (USR) light sources having electron emittances near the X-ray diffraction limit that would provide spectral brightness one or two orders of magnitude higher than present-day, 3rd generation sources and very large coherent flux in the multi-keV photon energy range [1]. At the same time, there is a growing scientific inte...

Toward the Slowing & Storage of Light

fundamental quantities in nature, underlies many of the basic properties of the universe. The velocity of a pulse of light propagating in any medium (homogeneous or inhomogeneous) is determined by the group index ng , a magnitude which should not be confused with the refractive index of the medium. The group velocity, given by vg=c /ng , where c is the speed of light in vacuum, is determined no...
