A 2021 experiment achieved the landmark milestone of nuclear fusion ignition, which data analysis has now confirmed – but attempts to recreate it over the last year haven’t been able to reach ignition again
11 August 2022
We have ignition. An analysis has confirmed that an experiment conducted in 2021 created a fusion reaction energetic enough to be self-sustaining, which brings it one step closer to being useful as a source of energy.
The fusion ignition took place on 8 August 2021 at the Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) in California, but NIF researchers haven’t been able to reproduce this landmark achievement since. They have spent the past year analysing the experimental conditions that …
