NIF: US lab takes further step towards nuclear fusion goal
US physicists confirm that they have achieved a stage in nuclear fusion called “burning plasma”. …
“In these experiments we achieved, for the first time in any fusion research facility, a burning plasma state where more fusion energy is emitted from the fuel than was required to initiate the fusion reactions, or the amount of work done on the fuel,” said Annie Kritcher, a physicist at the Lawrence Livermore National Laboratory (LLNL) where NIF is based.
