Helion's sixth prototype, Trenta, passes 100 million °C after a 16-month test campaign
Helion's sixth prototype, Trenta, achieved 100 million °C (9 keV) after a 16-month vacuum campaign, making it the first private company to report exceeding the temperature range needed for commercial fusion power plants.
- Trenta sustained 9 keV ion temperatures above 8 keV and electron temperatures of 1 keV.
- 16-month continuous operation under vacuum validated component lifetime and reliability for commercial power generation.
- Achievement validates Helion's path toward a cost-effective, zero-carbon electrical power plant with 24/7 generation.
