In-vessel and depth-resolved semi-quantitative analysis on hydrogen isotopes and wall materials in JET by LIBS operated on a remote handling arm Open
The tokamak JET achieved a groundbreaking milestone in nuclear fusion during its final deuterium–tritium experimental campaign (DTE-3) by setting a new world energy record [1]. To investigate in-vessel the fuel retention and wall material …
