Laboratory researchers describe how antineutrino detectors could aid in nuclear nonproliferation efforts

March 16, 2020- 
A tiny, invisible particle could offer help for a big problem — the threat of nuclear proliferation. For more than six decades, scientists have been developing instruments for fundamental physics that can detect antineutrinos, particles that have no electric charge, almost no mass and easily pass through matter. Antineutrinos are emitted in vast quantities by nuclear reactors, and since...

Nuclear diagnostics help pave way to ignition on NIF

March 12, 2020- 
At its peak, a NIF inertial confinement fusion (ICF) implosion lasts about 100 trillionths of a second. The imploded fuel is a hundred millionths of a meter in diameter and as much as eight times denser than lead. The center of the imploded capsule is a few times hotter than the core of the sun. Developing a clear understanding of exactly what’s happening in a NIF implosion under those...
