Synchrotron Science

The development of synchrotron radiation sources in Brazil is described from a brief historical point of view followed by a description of the Sirius project, a new 3 GeV fourth-generation synchrotron light source with 518 m circumference and 0.25 nm.rad emittance, in final construction stage at the Brazilian Synchrotron Light Laboratory campus, in Campinas. As one of the pioneer fourth-generation machines, many accelerator engineering challenges were studied in depth and resulted in quite a few innovative developments. In this paper, we review some of these developments. This article is part of the theme issue ‘Fifty years of synchrotron science: achievements and opportunities’.

Potential Target

Acinetobacter baumanniiis a common multidrug-resistant clinical pathogen that is often found in hospitals. TheA. baumanniiphosphoglycerate kinase (AbPGK) is involved in the key energy-producing pathway of glycolysis and presents a potential target for antibiotic development.AbPGK has been expressed and purified; it was crystallized using lithium sulfate as the precipitant. TheAbPGK crystals belonged to space groupP2221. They diffracted to a resolution of 2.5 Å using synchrotron radiation at the Canadian Light Source.

Absorption Features

We have investigated the optical absorption of CHCl3, CHBr3, and CHI3 in the vacuum ultraviolet, using synchrotron radiation as the light source. A number of absorption features have been observed and are assigned to n - σ*, n - s, n - p, and n - d, one electron excitations.

Radiation Sources

Infrared synchrotron radiation (IR-SR) is a broad-band light source. Its brilliance is the main advantage for microspectroscopy experiments, when the limited size of the sample often prevents the use of conventional thermal radiation sources. Cultural heritage materials are delicate and valuable; therefore, nondestructive experiments are usually preferred. Nevertheless, sometimes, small pieces can be acquired in the process of preservation and conservation. These samples are analyzed by various experimental techniques and give information about the original material and current condition. In this paper, four attempts to analyze cultural heritage materials are introduced. All these experiments are performed at the microspectroscopy station of IR beamline BL43IR in SPring-8.
