A tokamak in France set a new record in fusion plasma by encasing its reaction in tungsten, a heat-resistant metal that allows physicists to sustain hot plasmas for longer, and at higher energies and densities than carbon tokamaks.
A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing scientists to fiddle with the superheated material and induce fusion reactions. The recent achievement was made in WEST (tungsten (W) Environment in Steady-state Tokamak), a tokamak operated by the French Alternative Energies and Atomic Energy Commission (CEA).
WEST was injected with 1.15 gigajoules of power and sustained a plasma of about 50 million degrees Celsius for six minutes. It achieved this record after scientists encased the tokamak’s interior in tungsten, a metal with an extraordinarily high melting point. Researchers from Princeton Plasma Physics Laboratory used an X-ray detector inside the tokamak to measure aspects of the plasma and the conditions that made it possible.
“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. “We have reached a stationary regime despite being in a challenging environment due to this tungsten wall.”

New Fusion Record Achieved in Tungsten-Encased Reactor
A fusion device ensconced in highly durable tungsten sustained a more energetic, denser plasma than previously recorded.
