Heating Water Ultrafast
2013-12-16 12:25:16

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:...

Intense 2-color Double X-ray Laser Pulses Generated For First Time
2013-12-04 12:47:43

RIKEN A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are very powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions. SACLA is one of only two facilities in the world to...

Accelerator On A Chip
2013-09-28 04:45:02

redOrbit Staff & Wire Reports - Your Universe Online A new technique used by researchers from the US Department of Energy's SLAC National Accelerator Laboratory and Stanford University could dramatically reduce the size of particle accelerators. The scientists used a laser to accelerate electrons at 10 times that of conventional technology, doing so in a nanostructured glass chip smaller than a grain of rice. Their breakthrough could result in new medical and scientific devices that...

Powerful X-Ray Lets Researchers Watch Chemical Reactions In Real Time
2013-03-15 10:08:39

redOrbit Staff & Wire Reports - Your Universe Online Using an extremely fast and extremely powerful X-ray laser, researchers have successfully observed how a catalyst behaves during a chemical reaction — work that they claim could be an important step forward in the search for cleaner and more efficient sources of energy. Catalysts are substances that modify and increase the rate of a chemical reaction without being consumed in the process, and they are essential to the...

New Hope For Sleeping Sickness Drug
2012-11-30 12:32:48

Connie K. Ho for redOrbit.com — Your Universe Online Scientists from the Helmholtz Association of German Research Centers and the Department of Energy´s (DOE) SLAC National Accelerator Laboratory recently revealed that X-rays could provide information on a novel biological structure that could possibly be developed into a sleeping sickness drug. The findings were discovered with the help of a free-electron laser that is considered the most powerful in the world. Sleeping...

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...

Measuring State Of The Art Beams In Table Top Accelerator
2012-10-25 09:00:23

Studies by Berkeley Lab scientists of electron beam quality in laser plasma accelerators include novel tests for slice-energy spread Part Two: Slicing through the electron beam Wim Leemans of Berkeley Lab´s Accelerator and Fusion Research Division heads LOASIS, the Laser and Optical Accelerator Systems Integrated Studies, an oasis indeed for students pursuing graduate studies in laser plasma acceleration (LPA). Among the most promising applications of future table-top accelerators...

Table Top Accelerators To State Of The Art Beams
2012-10-22 15:34:11

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...

Scientists employ a powerful laser to breathe new life into an old technology for studying atomic-level structures A multi-university team has employed a high-powered laser to dramatically improve one of the tools scientists use to study the world at the atomic level. The team was able to use their amped-up electron paramagnetic resonance (EPR) spectrometer to study the electron spin of free radicals and nitrogen atoms trapped inside a diamond. The improvement will pull back the veil...

BELLA Laser Achieves One Pulse Per Second For World Record Power
2012-07-27 12:07:54

BELLA Laser Achieves One Pulse Per Second For World Record Power As Berkeley Lab´s laser plasma accelerator project BELLA nears completion, its drive laser has delivered one petawatt — a quadrillion watts — of peak power once each second, a world record for laser performance On the night of July 20, 2012, the laser system of the Berkeley Lab Laser Accelerator (BELLA), which is nearing completion at the U.S. Department of Energy´s Lawrence Berkeley National...

Word of the Day
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
'Cacodemon' comes from a Greek term meaning 'evil genius.'
