Meeting Reports: Summer School in Synchrotron Radiation Science

The ancient city of Chester close to the Welsh border, with its Roman foundations and medieval buildings, played host to the first part of the second in a new series of international summer schools organized by the SRS, held from August 31 to September 10, 2004. Thirty research students and postdoctoral researchers came from a range of scientific disciplines, including physics, chemistry, materials science and engineering, biology, earth and environmental sciences, and from many countries in Europe and the Middle East, to take part. There was a particularly strong contingent from countries associated with the Sesame project to develop SR facilities in the Middle East (http://www.sesame.org.jo/).     

Meeting Reports: BioCD-2005 Workshop

An intensive weeklong course on Circular Dichroism (CD) was presented at the National Synchrotron Light Source (NSLS), Brookhaven National Laboratory (BNL), from June 20-24, 2005. CD is the difference in absorption of left and right circularly polarized light. It is observed in the spectral regions of absorption of molecules that are chiral, i.e., lacking a center of symmetry. While most CD spectra are small—only a tiny fraction of the total absorption biopolymers with helical structures—such as proteins, DNA, RNA and polysaccharides, exhibit informative CD spectra. The objective of BioCD-2005 was to acquaint the participants with the theory of ultraviolet CD spectroscopy.     

Meeting Report: Fifth International Conference on Synchrotron Radiation in Materials Science

More than 250 scientists from 22 countries gathered in Chicago, Illinois, from July 30 to August 2, 2006, to participate in the Fifth International Conference on Synchrotron Radiation in Materials Science (SRMS-5). The SRMS conference is held every two years, bringing together leading-edge researchers in the materials sciences making use of synchrotron radiation. The conference, which was organized and hosted this year by Argonne National Laboratory and the Advanced Photon Source, provided an overview of the latest research developments in a broad range of areas, such as polymers and biomaterials, magnetic and superconducting materials, glasses and ceramics, engineering materials, materials under extreme conditions, complex oxides, innovative instrumentation, membranes, and thin films. The aim of SRMS-5 was to highlight recent breakthroughs in materials science using synchrotron radiation and to open doors to future innovation and discovery.     

Meeting Reports: SSRL Structural Molecular Biology Summer School 2005

The fifth Structural Molecular Biology (SMB) Summer School (SMB) was held at the Stanford Synchrotron Radiation Laboratory (SSRL) from September 12-15, 2005. This year the school focused on two synchrotron-based techniques: X-ray absorption spectroscopy and macromolecular crystallography and the application of these techniques to biological problems. This year’s Summer School was attended by 21 students and taught by a team of 14 tutors. It consisted of a day and a half of lectures, followed by two days of rotating practical sessions, concluding with another half-day of lectures on advanced topics in synchrotron-based structural molecular biology.     

Ninth Asia Oceania Forum for Synchrotron Radiation Research

Meeting Report: Third Italian-Australian Workshop on Spectroscopy and Imaging with Synchrotron Radiation

The third Italian-Australian Workshop on Spectroscopy and Imaging with Synchrotron Radiation (IAW) was held at the Australian Synchrotron on April 14, 2007, and was the first scientific meeting held there. Previous workshops have been held in Trieste (2005) and Lorne, Victoria (2003). Indeed, when the first meeting was held, the Australian synchrotron was an idea and now it is a reality.     

Synchrotron Radiation Research in Italy: The Early Years

The use of synchrotron radiation (SR) at the National Laboratories of Frascati (LNF) goes back in time. As early as the 1960s, a group of physicists and engineers under the leadership of B. Touschek [1 C. Bernardini, Il Nuovo Saggiatore 27, 6 (1986). [Google Scholar]] was involved in the pioneering work on the first storage ring “Anello di Accumulazione” (AdA) (Figure 1).

The oral presentations featured 7 plenary speakers, 26 invited speakers, and 115 symposia speakers selected from abstracts. A fully booked trade exhibition housing 33 trade displays was located in the adjoining Exhibition Centre along with an extensive poster display. Two poster sessions showcasing a total of 450 posters were held on the Tuesday and Thursday afternoons of the conference.

Topics in Coherent Synchrotron Radiation: Experimental Consequences of Radiation Impedance

Coherent synchrotron radiation (CSR) is now an established source of radiation in the terahertz region, with flux capabilities many orders of magnitude higher than conventional SR sources. Accordingly, CSR is playing an ever-increasing role in the field of Far-IR spectroscopy at synchrotron facilities around the world. However, with the improvement in spectroscopic resolution, the incident CSR spectra from several facilities are displaying intensity profiles that appear to be modulated by periodic peaks or deep indentations, while theory predicts a featureless distribution. After eliminating the usual suspects, like multiple reflections from windows, etc., one looks for a deeper explanation, such as the role played by the radiation impedance. This impedance is largely defined by the vacuum chamber in the region of the bend magnets, but probably with some effects from the straight sections as well.
