“The fact that we were able to raise the triple product to tokamak level with long plasma duration times marks another important milestone on the way to a stellarator suitable for power plants.”
Wendelstein 7-X held a tokamak-level triple product for 43 seconds by firing about 90 frozen hydrogen pellets into the plasma. The record only counts for long discharges. JET and JT60U still lead by a clear margin on short pulses, and both are shut down. Nobody claims net energy.
