Stark Broadening of Hydrogen Lines in Magnetic Fusion Plasmas

19th International Conference on Atomic Processes in Plasmas (APiP), Campus Les Cordeliers, Paris, FRANCE, APR 04-08, 2016International audienceWe report on a Stark line shape model for the diagnostic of tokamak edge plasmas. In specific scenarios, plasma discharges are carried out at high density regimes, sufficiently so that the spectral lines emitted by the neutral atoms present in the edge and in the divertor region are affected by the plasma microscopic electric field (Stark broadening). We present new line shape calculations, carded out for diagnostic purposes in the context of the MST]. (Medium Sized Tokamak) European campaign. The role of the magnetic field (Zeeman effect) on line spectra is discussed
