Bright Thinking Leads to Breakthrough in Nuclear Threat Detection Science

Scintillator_comparison_sm.jpg

Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America’s ports and borders.

It’s been a challenge for Sandia National Laboratories' Tonopah Test Range to keep decades-old equipment running while gathering detailed information required for 21st century non-nuclear testing. The Nevada test range has changed the analog brains in instruments to digital, moved to modern communications systems, and upgraded telemetry and tracking equipment and computing systems.

Food in Japan will be contaminated by low-level radioactivity for decades following the 2011 Fukushima nuclear disaster, but not at a level which poses a serious risk to human health, according to new research.

Northwestern’s astrophysics center, CIERA (the Center for Interdisciplinary Research and Exploration in Astrophysics), is leading a new crowdsourcing project called Gravity Spy to sift through the massive amounts of data being produced by the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors located in the U.S.

The World’s Most Powerful X-Ray Laser Beam Creates ‘Molecular Black Hole’

MolecularBlackHole.jpg

When scientists at the Department of Energy’s SLAC National Accelerator Laboratory focused the full intensity of the world’s most powerful X-ray laser on a small molecule, they got a surprise: A single laser pulse stripped all but a few electrons out of the molecule’s biggest atom from the inside out, leaving a void that started pulling in electrons from the rest of the molecule, like a black hole gobbling a spiraling disk of matter.

JSA Names Charles Perdrisat and Charles Sinclair as Co-Recipients of its 2017 Outstanding Nuclear Physicist Prize

Jefferson Science Associates, LLC, announced today that Charles Perdrisat and Charles Sinclair are the recipients of the 2017 Outstanding Nuclear Physicist Prize. The 2017 JSA Outstanding Nuclear Physicist Award is jointly awarded to Charles Perdrisat for his pioneering implementation of the polarization transfer technique to determine proton elastic form factors, and to Charles Sinclair for his crucial development of polarized electron beam technology, which made such measurements, and many others, possible.

Neutron Lifetime Measurements Take New Shape for in situ Detection

RSI052705-Morris-NeutronLifetime.jpg

Neutrons are inherently unstable and don’t last long outside an atomic nucleus, and because they decay on a time scale similar to the period for Big Bang Nucleosynthesis, accurate simulations of the BBN era require thorough knowledge of the neutron lifetime, but this value is still not precisely known. This week in Review of Scientific Instruments, scientists at Los Alamos National Lab report an exciting new method to measure it.
