7-Jul-2015 Big PanDA and Titan merge to tackle torrent of LHC's full-energy collision data
With the successful restart of the Large Hadron Collider, now operating at nearly twice its former collision energy, comes an enormous increase in the volume of data physicists must sift through to search for new discoveries. Fortunately, a remarkable data-management tool developed by physicists at Brookhaven National Laboratory and the University of Texas at Arlington is evolving to meet the big-data challenge.
6-Jul-2015 Scientists drive tiny shock waves through diamond
Researchers have used an X-ray laser to record, in detail never possible before, the microscopic motion and effects of shock waves rippling across diamond. The technique, developed at the Department of Energy's SLAC National Accelerator Laboratory, allows scientists to precisely explore the complex physics driving massive star explosions, which are critical for understanding fusion energy, and to improve scientific models used to study these phenomena.
6-Jul-2015 Upgrades to ATLAS and LHC magnets for Run 2 and beyond
At the beginning of June, the Large Hadron Collider at CERN, the European research facility, began smashing together protons once again. Physicists at Brookhaven National Laboratory were busy throughout Long Shutdown 1, undertaking projects designed to maximize the LHC's chances of detecting rare new physics as the collider reaches into a previous unexplored subatomic frontier.
30-Jun-2015 Homegrown solution for synchrotron light source
Scientists at the US Department of Energy's Ames Laboratory have made advances in angle-resolved photoemission spectroscopy (ARPES) to help better study electronic properties of new materials.
29-Jun-2015 Magnetic attraction
Researchers studying a broad spectrum of science, including biofuel production processes, climate effects on carbon cycling in the soil and carbon transformations in the atmosphere will soon have access to EMSL's new 21 Tesla Fourier transform ion cyclotron resonance mass spectrometer. Scientists are eager to start getting molecular-level information for their research, and six inaugural studies were selected to use the new instrument through a Special Science Call.
19-Jun-2015 SLAC research resumes at upgraded Large Hadron Collider
Research with the Large Hadron Collider has officially resumed: The world's largest particle accelerator at CERN began on June 3 to collect data at a new record energy that could hold the key to new scientific discoveries. To keep up with the boost in performance, researchers at the Department of Energy's SLAC National Accelerator Laboratory have developed new technologies for ATLAS -- one of two experiments involved in the 2012 discovery of the Higgs boson.
18-Jun-2015 Adapting nanoscience imaging tools to study ants' heat-deflecting adaptations
A new study shows that the tiny hairs of Saharan silver ants possess crucial adaptive features that allow the ants to regulate their body temperatures and survive the scorching hot conditions of their desert habitat. To study how the hairs allow the creatures to control electromagnetic waves in this manner, the Columbia Engineering research team turned to the resources and expertise available at Brookhaven Lab's Center for Functional Nanomaterials.
15-Jun-2015 What the blank makes quantum dots blink?
Quantum dots promise an astounding range of applications, if scientists can conquer their annoying habit of blinking. Researchers computing at NERSC recently ran simulations that offer new insights into the problem.
28-May-2015 Carbon nanothreads from compressed benzene
The thinnest possible linear thread that still retains a diamond-like structure was created by the extreme compression and decompression of the common chemical benzene. The threads may have outstanding mechanical and electronic properties. Further, the synthesis method opens up possible variations that could lead to materials presently unknown or impossible to make with existing techniques.
27-May-2015 Spiraling laser pulses could change the nature of graphene
A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.
21-May-2015 Shape-shifting plastic
Researchers from Oak Ridge National Laboratory, Washington State University and the University of Idaho have developed a process to make a thermoset that can be reshaped and reused. The new plastic is a shape-memory polymer, so named because the material can 'remember' its original shape and return to it after being deformed with heat or other forces.
20-May-2015 SLAC gears up for dark matter hunt with LUX-ZEPLIN
The US Department of Energy (DOE) recently signed off on the conceptual design of the proposed LUX-ZEPLIN (LZ) experiment and gave the green light for the procurement of some of its components. DOE's SLAC National Accelerator Laboratory, a key member of the LZ collaboration, is setting up a test stand for the detector prototype and a facility to purify liquid xenon, which will be the detector's 'eye' for dark matter.
18-May-2015 Optical diagnostics researcher at Sandia wins DOE Early Career award
Sandia National Laboratories researcher Christopher Kliewer has won a $2.5 million, five-year Early Career Research Program award from the Department of Energy's Office of Science for his fundamental science proposal to develop new optical diagnostic tools to study interfacial combustion interactions that are major sources of pollution and vehicle inefficiency.
12-May-2015 ORNL group leads calorimeter upgrade for Large Hadron Collider experiment
Run-2 for the Large Hadron Collider -- the world's largest and most powerful particle collider -- began April 5 at CERN. In preparation, Thomas M. Cormier, who leads the LHC Heavy Ion group at Oak Ridge National Laboratory, led an upgrade of the electromagnetic calorimeter used for LHC's experiment called ALICE (for A Large Ion Collider Experiment). This detector measures the energies of high-energy electrons and gamma rays emitted from the quark-gluon plasma.
12-May-2015 Construction of LSST clean room at SLAC completed
Engineers and scientists at the Department of Energy's SLAC National Accelerator Laboratory working on the Large Synoptic Survey Telescope (LSST) gathered on May 8 to celebrate the completion of a new clean room, where they will soon begin to assemble the largest digital camera ever built.
10-May-2015 Metamaterials shine bright as new terahertz source
Terahertz waves are used in information, communication, processing, and data storage technologies, yet few terahertz sources are available due to the limitations of natural materials. Scientists discovered an efficient terahertz emission from two-dimensional arrays of gold split-ring resonator metamaterials, which allow design and use of light-matter interactions at a fundamental level. This discovery opens new ways to use such materials.
8-May-2015 SLAC researcher receives DOE 'Early Career' grant to support X-ray optics and imaging
Anne Sakdinawat, an associate staff scientist at the Department of Energy's SLAC National Accelerator Laboratory, has been recognized with a prestigious DOE Early Career Research Program grant to advance her work in creating and using next-generation focusing and imaging devices for X-ray experiments at SLAC and other research sites.
8-May-2015 Intertwining of superconductivity and magnetism
Experiments reveal nearly static, spatially modulated magnetism in a copper-oxide superconductor. Because static magnetism and superconductivity prefer not to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory. This study will assist in developing a predictive theory for high-temperature superconductivity that can assist in the design and discovery of improved superconductors.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
