New findings could help scientists tame damaging heat bursts in fusion reactors

Picture strong wind blowing against a tree until it's knocked down. Such action would mimic the process that causes damaging heat bursts called edge localized modes (ELMs) to flare up in fusion facilities called tokamaks, which scientists use to develop on Earth the fusion energy that powers the sun and stars. Such heat bursts normally occur when the pressure at the edge of the hot plasma gas that fuels fusion reactions reaches a peak, causing heat to erupt against the walls of the tokamak, much like a tree finally toppling in a growing wind.
