"The accurate determination of the gamma-ray-to-neutron branching ratio for the deuterium-tritium reaction paves the way for using absolute gamma ray counting as a secondary and neutron-independent ...

The 3-D current density and 2-D magnetic fields during the pinch simulation. In the 3D image, the red color represents positive current, while the blue color represents negative current. The 2D image ...

General Fusion, the Vancouver-based fusion energy startup, reported a record fusion neutron yield from its LM26 magnetized target fusion machine after compressing a deuterium plasma with an imploding ...

Physicists measure these nuclear collision energies in kiloelectronvolts (keV). Today’s fusion reactors tend to operate ...

PDD neutron sources are capsules filled with deuterium-tritium (DT) gas at ambient temperature and shot with robust laser pulses that do not require stringent laser power contrast control or power ...

ORNL hosts two of the world’s most powerful sources of neutrons for research, the High Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS). ORNL is the U.S. epicenter for one of the ...

Pulsed neutron density measurement techniques deploy brief, intense bursts of high-energy neutrons into subsurface formations to probe material density. As neutrons scatter off atomic ...
