Not All Ions in Tokamaks Go with the Flow
Spectroscopic measurements reveal that main ions flow much faster than impurities at the edge of fusion-relevant plasmas.

U.S. and Korean scientists show how to find and use beneficial 3-D field perturbations to stabilize dangerous edge-localized modes in plasma.
Enabling beams to respond to plasma conditions in real time allows scientists to avoid instabilities and raise performance.
2-D velocity imaging helps fusion researchers understand the role of ion winds (aka flows) in the boundary of tokamak plasmas.
Just like lightning, fusion plasmas contain odd electromagnetic whistler waves that could control destructive electrons in fusion reactors.
Microwave heating significantly alters Alfvén waves, offering insights into the physics of the waves themselves.
International collaborators advance physics basis for tokamak plasma confinement at low rotation, potentially benefiting a fusion reactor.
Fast imaging of frozen argon pellets enables measurement of fast electrons formed during disruption for first time.
Heating the core of fusion reactors causes them to develop sheared rotation that can improve plasma performance.
Real time steering of microwave beams is used to suppress deleterious modes on DIII-D.
Recent experiments have confirmed the great potential of a novel plasma-material interface concept.
