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.

Manipulating Electron Spins Without Loss of Information
19.07.2017 | Universität Basel
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
