Energy recovery linacs as synchrotron light sources

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.

Light Sources using Energy Transfer from Excimer to Line Radiation

Efficient energy transfer between neon excimer molecules and hydrogen has been found. A small, high gas density light source has been developed, emitting entirely on the hydrogen 2p-l s transition at I 21 .567nm (Lyman-a). Light output densities of lOW/cm2 are obtained. Electron beam energy conversion efficiencies of lO% have been measured.

Fourth Generation Light Sources

Concepts and designs are now being developed at laboratories around the world for light sources with performance levels that exceed present sources, including the very powerful and successful third generation synchrotron radiation sources that have come on line in the past few years. Workshops[1,2], have been held to review directions for future sources. A main thrust is to increase the brightn...

Light Sources with Unknown

This paper reconsiders the familiar case of photometric stereo under the assumption of Lambertian surface reeectance and three distant point sources of illumination. Here, it is assumed that the directions to and the relative strengths of the three light sources are not known a priori. Rather, estimation of these parameters becomes part of the problem formulation. Each light source is represent...
