A unique colour X-ray camera went into operation at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). With this camera, it will be possible for the researchers at the Helmholtz Institute Freiberg for Resource Technology (HIF), a part of the HZDR, to determine within a very short period of time the concentrations of such very finely dispersed metals as rare earth elements in ore minerals. The scientists celebrated the start of the camera's routine operation together with colleagues, partners, and companies who participated in the assembly of the camera. It was developed specifically to meet the institute's analytical requirements.

The world's sharpest X-ray beam shines at DESY. At the X-ray light source PETRA III, scientists from Göttingen generated a beam with a diameter of barely 5 nanometres - this is ten thousand times thinner than human hair. This fine beam of X-ray light allows focusing on smallest details. The research groups of Professor Tim Salditt from the Institute of X-ray Physics and of Professor Hans-Ulrich Krebs from the Institute of Materials Physics of the University of Göttingen published their work in the research journal Optics Express.

Researchers have for the first time created an X-ray laser based on a solid. The method developed at DESY's free-electron laser FLASH opens up new avenues of investigation in materials research, as reported by the team of Prof. Alexander Föhlisch of the Helmholtz Zentrum Berlin (HZB) in the journal Nature. "This technology makes it possible to analyse sensitive samples that otherwise are quickly destroyed by intense X-ray light," notes co-author Prof. Wilfried Wurth of the University of Hamburg and the Hamburg Center for Free-Electron Laser Science (CFEL), a collaborative effort by DESY, the Max Planck Society and the University of Hamburg.

X-ray free-electron lasers (XFELs) produce higher-power laser pulses over a broader range of energies compared with most other x-ray sources. Although the pulse durations currently available are enormously useful for the study of materials, even shorter pulses are needed to observe features such as electrons at subatomic scales. Takashi Tanaka from the Riken SPring-8 Center has now proposed a theoretical pulse-amplification scheme that allows for the production of ultrashort x-ray pulses at extremely high energies.

A dramatic leap forward in the ability of scientists to study the structural states of macromolecules such as proteins and nanoparticles in solution has been achieved by a pair of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have developed a new set of metrics for analyzing data acquired via small angle scattering (SAS) experiments with X-rays (SAXS) or neutrons (SANS). Among other advantages, this will reduce the time required to collect data by up to 20 times.

PI miCos - Specialist for Precise Positioning Systems in a Vacuum: A wide variety of applications in microscopy or optical measurement technology require a sample or an optical element to be positioned in a vacuum of up to 10-11 hPa. One approach consists of positioners with vacuum stepper motors - from simple linear or rotation units to Hexapods and spacefabs that allow six-axis positioning in the smallest spaces with high accuracies of a few micrometers.

To obtain volumetric information on the chemical composition inside objects, a full-field micro X-ray fluorescence (microXRF) imaging technique has been implemented. Opposed to the traditional point-by-point methods using confocal imaging, this new method collects complete 2D XRF projections of 3D objects without any scanning. And in contrast with EDX surface mapping in an SEM, having complete information from the entire volume allows creating 3D XRF images non-destructively by tomographic reconstruction.
