Fundamental questions that particle physicists have pondered for decades might be answered when a $9.2 million neutron physics beam line is built at the Department of Energys Spallation Neutron Source on Chestnut Ridge.
At the core of physicists excitement is the fact that the SNS will produce up to 100 times more neutrons than are produced by any comparable source in the world. Tapping in to those neutrons will be the Fundamental Neutron Physics beam line, which will help physicists exploit neutrons to learn more about the Big Bang, left-right symmetry of the universe and the amount of energy produced in the sun. Recently, the beam line project passed a milestone with the approval of the performance baseline -- known as Critical Decision 2.
"This is, in a sense, the formal definition of the scope of the project and represents a detailed agreement between DOE and Oak Ridge National Laboratory as to what will be built, when it will be built, how much it will cost and how the project will be managed," said Geoff Greene, a professor at the University of Tennessee and researcher in the Physics Division at ORNL.

Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
