PALO ALTO, Calif., July 8, 2014 /PRNewswire/ -- Communications & Power Industries LLC (CPI) has received a contract totaling more than $6 million to provide power couplers for the European XFEL superconducting linear accelerator. Power couplers, which transmit the electromagnetic energy generated by a high-power microwave source, are critically important components in all superconducting accelerators, as they provide the vacuum and thermal interface between the evacuated...

Scientists Spin Cellulose Fibers That Are Stronger Than Steel
2014-06-02 12:24:56

Deutsches Elektronen-Synchrotron DESY A Swedish-German research team has successfully tested a new method for the production of ultra-strong cellulose fibers at DESY's research light source PETRA III. The novel procedure spins extremely tough filaments from tiny cellulose fibrils by aligning them all in parallel during the production process. The new method is reported in the scientific journal Nature Communications. "Our filaments are stronger than both aluminium and steel per...

Deutsches Elektronen-Synchrotron (DESY) Analysis allows tailoring materials for switchable windows and solar cells With DESY’s X-ray light source PETRA III, Danish scientists observed the growth of nanoparticles live. The study shows how tungsten oxide nanoparticles are forming from solution. These particles are used for example for smart windows, which become opaque at the flick of a switch, and they are also used in particular solar cells. The team around lead author Dr. Dipankar...

Gas giant Jupiter

April Flowers for redOrbit.com - Your Universe Online An international team of researchers recently got a sneak peek deep into the lower atmospheric layers of gas giant planets such as Jupiter or Saturn using Deutsches Elektronen-Synchrotron's (DESY) X-ray laser FLASH. The team's observations, led by Dr. Ulf Zastrau of the University of Jena, demonstrate how liquid hydrogen becomes a plasma. The findings, published in Physical Review Letters, also provide information on the material's...

Heating Water Ultrafast

DESY Novel method opens new paths for experiments with heated samples of biological relevance Scientists from the Hamburg Center for Free-Electron Laser Science have devised a novel way to boil water in less than a trillionth of a second. The theoretical concept, which has not yet been demonstrated in practice, could heat a small amount of water by as much as 600 degrees Celsius in just half a picosecond (a trillionth of a second). That is much less than the proverbial blink of an eye:...

Solar Cell Degradation Seen Directly For The First Time
2013-12-09 16:02:32

DESY X-ray Examination Shows Structural Changes In "Plastics" Solar Cells With the help of DESY’s X-ray light source PETRA III, researchers of Technische Universität München have, for the first time, watched organic solar cells degrade in real time. This work could open new approaches to increasing the stability of this highly promising type of solar cell. The team headed by Prof. Peter Müller-Buschbaum from the Technische Universität München (Technical University of Munich)...

World's Sharpest X-ray Beam Shines At DESY
2013-09-30 11:42:20

Deutsches Elektronen-Synchrotron DESY 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 nanometers – this is ten thousand times thinner than a 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...

Synchrotron Helps Reveal Structure Of A Supercooled Liquid
2013-07-05 10:54:23

Saarland University The experimental work, which was performed at the German Electron Synchrotron Facility (DESY) in Hamburg, involved levitating hot metal droplets and observing them as they cooled by irradiating them with x-rays from one of the world's strongest x-ray sources. The research work is funded by the German Research Foundation (DFG) and the results have just been published in Nature Communications. Supercooled liquids demonstrate some interesting phenomena when they are...

Promising target for the development of novel drugs With the X-ray vision of DESY's light source DORIS, a research team from Hamburg and Iceland has uncovered the molecular structure of a master regulator central to the most deadly form of skin cancer, melanoma. The results, published in the scientific journal "Genes & Development", throw new light on the workings of the so-called Microphthalmia-associated Transcription Factor MITF, that is not only connected to skin cancer, but also...

Supercharged Atoms Force Rethink On Existing Theories
2012-11-12 12:21:38

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has created ionized xenon atoms so positively charged that scientists involved in the study are now saying the existing theories need to be reexamined. Using the world´s most powerful laser, the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory at Stanford University, the physicists were able to kick out up to 36 electrons from a...
