Research Quality X-rays Could Have Widespread Applications
2013-11-25 08:27:00

University of Nebraska-Lincoln Using a compact but powerful laser, a research team at the University of Nebraska-Lincoln has developed a new way to generate synchrotron X-rays. Although the high quality of synchrotron X-rays make them ideal for research ranging from the structure of matter to advanced medical images, access to the technology has been limited until now. Most traditional synchrotron X-ray devices are gigantic and costly, available only at a few sites around the world....

Measuring State Of The Art Beams In Table Top Accelerator

Berkeley Lab´s lead in laser plasma acceleration research continues with new benchmarks for electron beam quality Part One: Focusing in on beam focus The rapidly evolving technology of laser plasma accelerators (LPAs) — called “table-top accelerators” because their length can be measured in centimeters instead of kilometers — promises a new breed of machines, far less expensive and with far less impact on the land and the environment than today´s...

How Light Changes Matter Measured By Synchronized Lasers
2012-08-29 14:06:05

Berkeley Lab scientists and their colleagues have successfully probed the effects of light at the atomic scale by mixing x-ray and optical light waves at the Linac Coherent Light Source Light changes matter in ways that shape our world. Photons trigger changes in proteins in the eye to enable vision; sunlight splits water into hydrogen and oxygen and creates chemicals through photosynthesis; light causes electrons to flow in the semiconductors that make up solar cells; and new devices for...

For the first time, an experiment shows that atomic nuclei can become transparent At the high-brilliance synchrotron light source PETRA III, a team of DESY scientists headed by Dr. Ralf Röhlsberger has succeeded in making atomic nuclei transparent with the help of X-ray light. At the same time they have also discovered a new way to realize an optically controlled light switch that can be used to manipulate light with light, an important ingredient for efficient future quantum...

Ability to probe deep below material surfaces should be boon for nanoscale devices The expression "beauty's only skin-deep" has often been applied to the chemistry of materials because so much action takes place at the surface. However, for many of the materials in today's high technologies, such as semiconductors and superconductors, once a device is fabricated it is the electronic structures below the surface, in the bulk of the material or in buried layers, that determine its...

New multiferroic mechanism could lead to next-generation memory and sensing devices Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have observed a new way that magnetic and electric properties "” which have a long history of ignoring and counteracting each other "” can coexist in a special class of metals. These materials, known as multiferroics, could serve as the basis for the next generation of faster and energy-efficient logic, memory, and...

Researchers can now see objects more precisely and faster at the nanoscale due to utilising the full color spectrum of synchrotron light, opening the way for faster 3D nanoimaging. This new methodology will provide for enhanced nanoimaging for studying bio samples for medical research, improved drug development and advanced materials for engineering. Using the Advanced Photon Source, a synchrotron facility in Chicago, USA, researchers from the ARC Centre of Excellence for Coherent X-ray...

Scientists from Finland and France have developed a new synchrotron X-ray technique that may revolutionize the chemical analysis of rare materials like meteoric rock samples or fossils. The results have been published on 29 May 2011 in Nature Materials as an advance online publication. Life, as we know it, is based on the chemistry of carbon and oxygen. The three-dimensional distribution of their abundance and chemical bonds has been difficult to study up to now in samples where these...

Chemical images now much more detailed With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, a physicist at the University of Wisconsin-Milwaukee (UWM), led a team of researchers from UWM, the University of Illinois at Urbana-Champaign and University of Illinois at Chicago (UIC) to demonstrate these new capabilities....
