Synchrotron Radiation Sources for the Future
1. Introduction Synchrotron sources have proven to be immensely important research tools throughout the biological, physical and engineering sciences. This is illustrated by the fact that most issues of Science or Nature are likely to contain articles which depended on synchrotron radiation (SR). Worldwide , about 70 SR sources are in various stages of operation, construction, or planning, repr...
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 کاملTraveling Wave Undulators for FELs and Synchrotron Radiation Sources
We study the use of a traveling wave waveguide as an undulator for short wavelength free-electron lasers (FELs) and synchrotron radiation sources. This type of undulator -which we will call TWUcan be useful when a short electron oscillation period and a large aperture for the propagation of the beam are needed. The availability of high power X-band microwave sources, developed for the electron-...
متن کاملTechnological Challenges of Third Generation - . Synchrotron Radiation Sources
New “third generation” synchrotron radiation research facilities are now in construction in France, Italy, Japan, Taiwan and the USA. Designs for such facilities are being developed in several other countries. Third generation facilities are based on storage rings with low electron beam emittance and space for many undulator magnets to produce radiation with extremely high brightness and cohere...
متن کاملGauss-schell sources as models for synchrotron radiation.
Gauss-Schell light sources are considered as models for synchrotron radiation. These sources can be viewed as random superpositions of coherent Gaussian beams. The relationships of the various widths that can be defined for the description of intensity and coherence, as related to the widths of the electron beam and the single-electron radiation (diffraction) pattern, are summarized. The descri...
