PPPL researchers find that jumbled magnetic fields in the core of fusion plasmas can cause the entire plasma discharge to suddenly collapse.

Nuclear physicists from Argonne National Laboratory led an international physics experiment conducted at CERN that utilizes novel techniques developed at Argonne to study the nature and origin of heavy elements in the universe.

Researchers have developed a technique for determining the historical location and distribution of radioactive materials, such as weapons grade plutonium. The technique may allow them to use common building materials, such as bricks, as a three-dimensional 'camera,' relying on residual gamma radiation signatures to take a snapshot of radioactive materials even after they've been removed from a location.

Graz University of Technology researchers describe in Physical Review Letters how a molecule moves in the protective environment of a quantum fluid.

A summary of key points of the fusion and plasma science community's year-long Community Planning Process that proposes accelerating development of these strategic fields.

The article appears in the latest issue of Reviews of Modern Physics. In the paper, the scientists review current and projected readiness of various antineutrino-based monitoring technologies.

A single x-ray can unravel an enormous molecule, physicists report in the March 17 issue of Physical Review Letters. Their findings could lead to safer medical imaging and a more nuanced understanding of the electronics of heavy metals.

Injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performance. Studies by PPPL and ORNL physicists compared the two methods on the DIII-D National Fusion Facility, looking ahead to the fueling to be used on ITER.
