Diagnostics of active and eruptive prominences through hydrogen and helium lines modelling [PDF]
, 2008 In this study we show how hydrogen and helium lines modelling can be used to make a diagnostic of active and eruptive prominences. One motivation for this work is to identify the physical conditions during prominence activation and eruption. Hydrogen and

Plasma Diagnostics in View of ITER [PDF]
Fusion Science and Technology, 2010 The ITER environment imposes many challenges for the various diagnostic systems. At the one hand diagnostic functionalities are required that go well beyond those at present devices. This is because there is a need to actively control (the profiles of) multiple plasma parameters, implying that measurement systems should be accurate and reliable. At the

H-β Line in a Corona Helium Plasma: A Multi-Code Line Shape Comparison
Atoms, 2018 Many spectroscopic diagnostics are routinely used as techniques to infer the plasma parameters from line emission spectra, but their accuracy depends on the numerical model or code used for the fitting process.
