This issue brings together papers from the satellite meeting of the XVIII IUCr Congress held last August. The meeting covered topics ranging from thèsource to science'. Such an ambitious theme was appropriate given the location of the meeting, where the ®rst dedicated synchrotron radiation source was designed and built and from where the ®rst recognition of synchrotron radiation work in the for...

The studies in the VUV and soft-x-ray surface photophysics and photochemistry in the microscopic level using monochromatic synchrotron radiation is a new research category. In this article we employed the techniques of photon-stimulated desorption (PSD) of positive/negative ions and photoelectron spectroscopy (PES) to study the photolysis of molecules adsorbed on single crystal surface by monoc...

Synchrotron radiation is the most versatile way to explore biological materials in different states: monocrystalline, polycrystalline, solution, colloids and multiscale architectures. Steady improvements in instrumentation have made synchrotrons the most flexible intense X-ray source. The wide range of applications of synchrotron radiation is commensurate with the structural diversity and compl...

Free-electron lasers are radiation sources, based on the coherent emission of synchrotron radiation of relativistic electrons within an undulator or wiggler. The resonant radiation wavelength depends on the electron beam energy and can be tuned over the entire spectrum from micrometer to X-ray radiation. The emission level of free-electron lasers is several orders of magnitude larger than the e...
