  • The paper focuses on future developments of storage ring based synchrotron sources. It includes the major facility upgrades, the new generation of intermediate energy light sources under construction worldwide. Current developments are presented such as the studies of ultra small emittance rings as well as the generation of femtosecond pulses of radiation.
  • We show that the development of new materials and improvements of existing ones are at the root of the spectacular recent developments of new technologies for synchrotron storage rings and free-electron laser sources. This holds true for all relevant application areas, from electron guns to undulators, x-ray optics, and detectors. As demand grows for more powerful and efficient light sources, efficient optics, and high-speed detectors, an overview of ongoing materials research for these applications is timely. In this article, we focus on the most exciting and demanding areas of materials research and development for synchrotron radiation optics and detectors. Materialsmore » issues of components for synchrotron and free-electron laser accelerators are briefly discussed. Lastly, the articles in this issue expand on these topics.« less
  • At a number of construction sites around the world, crews are laboring in and around large circular tracks to install the accelerators and storage rings that will form the basis of new synchrotron radiation facilities. Most of the budding facilities are designed to produce synchrotron radiation, in the soft- or hard-x-ray regions, that is far brighter than available sources can provide. They are sometimes described as the third generation. According to this rough categorization, the first generation consists of circular accelerators originally intended for other purposes: they provide synchrotron radiation to parasitic experiments or, in some cases, they have becomemore » partially dedicated to such uses. The second generation comprises facilities specifically designed to support synchrotron radiation experiments, with the radiation produced primarily as electrons or positrons curved in a field of the machines' bending magnets. The third-generation machines, by contrast, are designed to optimize the radiation that is produced traverse devices known as wigglers and undulators. The new machines will complement existing facilities, and they will provide more opportunities for the growing user community.« less
  • A direct comparison has been made between the intensity of dispersed radiation from a laboratory Hopfield helium continuum and that obtained from the electron storage ring called Tantalus 1. The relative advantages and disadvantages of the respective light sources are described. Extrapolation of this information to other (present and future) electron storage-ring sources is discussed.
