14-May-2018 Made in the USA
'Made in the USA.' That can now be said of the radioactive isotope molybdenum-99 (Mo-99), last made in the United States in the late 1980s. Its short-lived decay product, technetium-99m (Tc-99m), is the most widely used radioisotope in medical diagnostic imaging. Tc-99m is best known for imaging blood flow in a cardiac nuclear stress test.
10-May-2018 Taking the stress out of residual stress mapping
Researchers from the University of Virginia are using neutrons to explore fundamental work in residual stress mapping that promises more precise science down the road for Oak Ridge National Laboratory and similar facilities around the world. The UVA team's research will provide insight into the accuracy of residual stress mapping measurements in such materials when the neutron beam must travel large distances through the sample.
9-May-2018 Whistler waves appear to scatter runaway electrons in fusion plasmas
When whistler waves are present in a fusion plasma, runaway electrons pay attention.
A research team led by the Department of Energy's Oak Ridge National Laboratory is the first to directly observe the elusive waves inside a highly energized magnetic field as electrons zoom around the plasma.
Using sophisticated technologies, the team made direct measurements of whistler waves produced when a laboratory plasma becomes unstable and generates runaway electrons.
2-May-2018 Shake rattle and code
Tom Jordan and a team from the Southern California Earthquake Center (SCEC) are using the supercomputing resources of the Argonne Leadership Computing Facility (ALCF), a US Department of Energy Office of Science User Facility, to advance modeling for the study of earthquake risk and how to reduce it.
