Spokespersons for CMS and ATLAS, the two biggest experiments at the Large Hadron Collider, announced yesterday that both experiments have found strong hints in their data of something that could be a low-mass Higgs boson – and added that they are well-situated to give a more definitive answer by the end of next year. But, as pointed out by SLAC physicist and ATLAS collaboration member Charlie Young, the salt shaker is still on the table.
After five night shifts of shooting pairs of X-ray pulses through soups of fine sand and gold, Aymeric Robert was tired but exhilarated. The first experiment with an instrument he helped bring into being – the X-ray Correlation Spectroscopy (XCS) instrument at SLAC’s Linac Coherent Light Source – had just ended, launching a new tool for understanding liquids, glasses and other less-than-orderly substances.
Sandy Merola, SLAC’s Chief Operating Officer, has a prominent role in a short video celebrating the 25th anniversary of ESnet, the pioneering high-bandwidth computer network that now connects thousands of DOE researchers at more than 40 different national laboratories and supercomputing facilities and links them to research partners worldwide.
In 2009, when biophysicist Ilme Schlichting and her colleagues applied to use the X-ray laser at SLAC’s Linac Coherent Light Source, they added a radical idea to their proposal: They would make all the data they collected on two viruses and a nanoparticle available to the public one year after the experiment ended.
Menlo Park, Calif. — If we could make plant food from nitrogen the way nature does, we’d have a much greener method for manufacturing fertilizer – a process that requires such high temperatures and pressures that it consumes about 1.5 percent of the world’s energy.
Using leftover high-speed electrons from SLAC’s Linac Coherent Light Source, researchers have successfully generated intense pulses of light in a largely untapped part of the electromagnetic spectrum – the so-called terahertz gap.
Fifteen years ago, SLAC National Accelerator Laboratory (SLAC) scientist Apurva Mehta volunteered to help a friend build beamline parts at the Stanford Synchrotron Radiation Lightsource (SSRL). Today, he's "still mucking around with beamlines."
In a paper published Nov. 2 in Nature Communications, a team of researchers led by University of Maryland's Ichiro Takeuchi, in collaboration with Stanford Synchrotron Radiation Lightsource's Apurva Mehta, reported the discovery of large magnetostriction in an iron/cobalt alloy — in other words, the alloy shows a mechanical strain when a magnetic field is applied.
A half-sized Fermi space telescope model, originally launched from SLAC's booth at the International Conference for High Performance Computing, Networking, Storage and Analysis, last year in New Orleans, has settled into a new orbit above the downstairs foyer at the Kavli Auditorium.
One of the most striking features of particle collisions is the jet: a spray of particles, or energy – or both – produced when hadrons, the quark-containing particles that give the Large Hadron Collider its name, slam together.
