Thermonuclear record: the WEST tokamak held plasma at 50 million °C for six minutes
The French tokamak WEST set a new record - it held plasma with a temperature of about 50 million degrees Celsius for 6 minutes. This was made possible by using the internal lining of the reactor with tungsten, a metal with an extremely high melting point of 3420 °C. Image source: Tokamak WEST/CEA-IRFM Source: 3dnews.ru
