"Achieving the conditions needed for ignition has been a long-standing goal for all inertial confinement fusion research and opens access to a new experimental regime where alpha-particle self-heating outstrips all the cooling mechanisms in the fusion plasma."
In the experiments performed to reach this ignition result, researchers heat and compress a central"hot spot" of deuterium-tritium fuel using a surrounding dense piston also made from deuterium-tritium, creating a super hot, super pressurized"Ignition occurs when the heating from absorption of α particles [two protons and two neutrons tightly bound together] created in the fusion process overcomes the loss mechanisms in the system for a duration of time," said the authors in...
This landmark result comes after years of research and thousands of man hours dedicated to improving and perfecting the process: over 1,000 authors are included in theDespite repeated attempts having not been able to achieve the same energy yield as the August 2021 experiment, all of them reached higher energies than previous experiments.
