Overview of New Light Sources
Over the past few years, the use of synchrotron light sources has continued to grow rapidly. Several new facilities are in various phases of development. This paper provides an overview of the new facilities that have been proposed, have started construction, or are being commissioned throughout the world. Several trends in the design and specification of these facilities are reviewed, and poss...
متن کاملNew synchrotron radiation sources and the next-generation light sources.
Last December, the Swiss Light Source (SLS) at the Paul Scherrer Institute, located close to Zurich, became the latest third-generation synchrotron radiation source to come on-line (see Editorial, March 2001). Since its ®rst stored beam (1.6 mA) on 19 December 2000, it has continued to make rapid progress towards user operation. In May 2001, a gap of 6.5 mm was achieved with an in-vacuum undula...
متن کاملNew source technologies and their impact on future light sources
Emerging technologies are critically evaluated for their feasibility in future light sources. We consider both new technologies for electron beam generation and acceleration suitable for X-ray free-electron lasers (FELs), as well as alternative photon generation technologies including the relatively mature inverse Compton scattering and laser high-harmonic generation. Laser-driven plasma wakefi...
متن کاملFourth 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...
متن کاملLight 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...
