The Institute for fusion sciences and instrumentation in nuclear environments draws on research teams within 10 research units and 2 joint laboratories with the CEA. It therefore connects around a hundred staff from Aix Marseille Université, the CNRS and Centrale Méditerranée as well as 150 CEA staff within the IRESNE and the IRFM. We also have 1 partner faculty with around 200 students enrolled on programmes attached to our institute and 3 partner doctoral schools in our scope with around 40 PhD students.
