'Tungsten wall' leads to nuclear fusion breakthrough
A fusion device ensconced in highly durable tungsten sustained a more energetic, denser plasma than previously recorded.
“These are beautiful results,” said Xavier Litaudon, a scientist with CEA and chair of the Coordination on International Challenges on Long duration OPeration (CICLOP), in a PPPL release. Tungsten has a higher melting point than carbon, and according to Korea’s National Research Council of Science and Technology, the new diverter improves the reactor’s heat flux limit two-fold. KSTAR’s new diverter enabled the institute’s team to sustain high-ion temperatures exceeding 100 million degrees Celsius for longer.
