ORNL’s pellet injector enables world record performance in W7-X

A key milestone in the pursuit of fusion energy is achieving a high “triple product,” an important metric of the temperature and density of a burning plasma and how well it is confined. The Wendelstein 7-X stellarator in Germany recently sustained a plasma with a record high triple product for 43 seconds – far surpassing previous performance – in part due to a novel fuel pellet injection system developed by researchers at ORNL.
