Triple product records (IMAGE)
Caption
In a future fusion power plant, a plasma with a high triple product (y-axis, logarithmic scale) must be maintained for long periods (x-axis). Previous fusion experiments only achieved high values for plasma durations of a very few seconds. On May 22, 2025, Wendelstein 7-X achieved the world record for plasma times of more than 30 seconds with a high fusion product. In this OP2.3 experiment campaign, further best values were achievedfor plasma durations between 30 and 40 seconds. Tokamaks remain the record holders for short plasma times.
