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

"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...

Image 1 - Illinois And Energy Dept. Invest $33M In Fermilab Research Center

Fermilab broke ground on Friday on a new Accelerator Research Center, where physicists will work on the development and industrialization of particle accelerator technology. Once completed in 2013, the 48,000-square-foot complex will wrap around Fermilab´s orange Collider Detector Facility building. The State of Illinois is providing $20 million to design and build a part of the complex, while the U.S. Department of Energy will contribute $13 million to refurbish an existing...

Physicists at Mainz University significantly improve the calculation method for scattering experiments in particle physics Scientists at Johannes Gutenberg University Mainz (JGU) have set a new record for the calculation of scattering amplitudes. This kind of calculation is used to predict the outcome of accelerator experiments in which high-energy particles collide with one another. However, the calculations become increasingly difficult the greater the number of orders the physicists...

New Light Cast On Electrons Heated To Several Billion Degrees
2011-11-21 13:57:00

A new class of high power lasers can effectively accelerate particles like electrons and ions with very intense, short laser pulses.  This has attracted the interest of researchers around the globe, working out the details of the acceleration process which occurs when a laser beam impinges on a thin foil to accelerate ions from the foil´s rear surface to high energies.  The electrons in the foil are heated by the laser pulse, thereby gaining energy.  These electrons in...

CERN Launches Upgrade Project For The Large Hadron Collider
2011-11-17 06:05:43

Physicists from around the world kicked off a major initiative on Wednesday to upgrade the Large Hadron Collider (LHC) at CERN -- the world´s leading laboratory for particle physics -- into a vastly more powerful space research machine by 2020. The work brings together scientists and engineers from some 14 European institutions, Japan and the United States, with the goal of developing new technologies in fields ranging from super-conducting magnets to energy transfer lines. While...

Word of the Day
  • A blustering, bullying fellow; a pot-valiant braggart; a bully.
This word is named for Draw-Can-Sir, a character in George Villiers' 17th century play The Rehearsal.
