X-rays Help Understand How Mechanical Action May Lead To Greener Chemistry
2012-12-03 10:33:46

European Synchrotron Radiation Facility Solvents are omnipresent in the chemical industry, and are a major environmental and safety concern. Therefore the large interest in mechanochemistry: an energy-efficient alternative that avoids using bulk solvents and uses high-frequency milling to drive reactions. Milling is achieved by the intense impact of steel balls in a rapidly moving jar, which hinders the direct observation of underlying chemistry. Scientists have now for the first time...

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

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...

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...

Record Setting 7.2 Trillion Degrees Fahrenheit In New York
2012-06-28 07:57:05

[ Watch the Video ] Lee Rannals for redOrbit.com As record-setting heat and wildfires continue to consume Colorado, one team of scientists has created a temperature so hot the Sun would melt. Scientists working with a giant atom smasher at New York's Brookhaven National Laboratory have created the hottest temperature ever seen on Earth, at 7.2 trillion degrees Fahrenheit. The excruciatingly hot temperature has been verified by the Guinness Book of Records, and confirmed as...

Airborne Particulates Investigated
2012-06-27 13:37:38

For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs -- usually without a trace. The structure of micron-size particulate matter is important in a wide range of fields from toxicology to climate science (tobacco smoke and oil smoke particles are typically one micron in size). However, its properties are surprisingly difficult to measure in...

Soot Particles Measured In Flight
2012-06-27 12:53:57

"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg. "This will have important implications for various fields from climate modelling to human health." CFEL is a joint venture of Deutsches Elektronen-Synchrotron DESY, the German Max Planck Society and the University of Hamburg. Aerosol particles like soot play...

Laser Lab Creates Bright X-ray Flashes
2012-06-07 12:44:30

At the Vienna University of Technology, a very special kind of bright coherent x-ray radiation has been created by an international team of scientists; the new method was presented in the current issue of Science A breakthrough in laser science was achieved in Vienna: In the labs of the Photonics Institute at the Vienna University of Technology, a new method of producing bright laser pulses at x-ray energies was developed. The radiation covers a broad energy spectrum and can therefore be...

CERN Scientists To Ramp Up LHC Output
2012-02-14 08:18:33

CERN physicists working at the Large Hadron Collider (LHC) near Geneva, Switzerland are to increase the machine´s energy output to embark on a last-ditch journey to find the elusive Higgs boson, a theoretical “God particle” that could change physics as we know it. Scientists say the 14 percent boost in the proton beams´ energies should improve the collider´s chances of finding “new physics” and definitively confirming or denying the existence of the...
