The new findings reveal through computer simulations a previously unknown role for the Biermann effect that could improve understanding of reconnection—the snapping apart and violent reconnection of magnetic field lines in plasmas that gives rise to northern lights, solar flares and geomagnetic space storms that can disrupt cell-phone service and electric grids on Earth.

Researchers at MIT's Plasma Science and Fusion Center (PSFC) have now demonstrated how microwaves can be used to overcome barriers to steady-state tokamak operation.  Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning—all in a package that's around a thousandth of the size of current accelerators.  The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities.  The authors designed a mechanism based on the deployment of a transport barrier to confine the particles and prevent them from moving from one region of the accelerator to another. "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said.  Now, in a new result unveiled today at the Neutrino 2018 conference in Heidelberg, Germany, the collaboration has announced its first results using antineutrinos, and has seen strong evidence of muon antineutrinos oscillating into electron antineutrinos over long distances, a phenomenon that has never been unambiguously observed.
