The Science and the people behind the news: Energy from Inertial Confined Fusion

In December of 2022 it was publicly announced that at the Lawrence Livermore National Laboratory (LLNL), the laser driven Indirect Inertial confinement fusion experiment at the National Ignition Facility (NIF), had achieved “ignition” on a layered Deuterium – Tritium (D-T) fuel in an imploding capsule. Namely, a plasma condition where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma. This breakthrough comes after researchers around the world have been engaged in this mission for more than 50 years, and at a time where energy from the fusion D,T atoms is at the core of a very much needed proof of principle as a near future feasible source of clean energy. Here we used the Open Research Knowledge Graph to put into perspective the last 14 years of experiments at NIF, showing the evolution of the difficulties, innovations and systematic achievements that a breakthrough experiment entails. At the time of the publication of this comparison, the results of December 2022 have not been published in a peer reviewed publication, hence an official technical press release is referred [Age of Ignition: Precise Changes Yield Historic Results LLNL-NEWS-Mar-23]•https://www.llnl.gov/news/designing-ignition-precise-changes-yield-historic-results . The comparison concentrates only on those experimental milestones that are highlighted by a notable increase in neutron yield; error bars are confined to the last 2 digits but are not quoted in this work; for further reading related references are quoted below. Future comparisons will address several specialized campaigns and related topics. Information from authoritative periodical resources, that disseminate groundbreaking events in science and technology for the general public, will be object of study in the same context.
