    Abstract

    This work strongly exploits the interdisciplinary links between astrophysical (such as the solar upper atmosphere) and aboratory plasmas (such as tokamak devices) by sharing the development of a common modelling for time-dependent onisation. This is applied to the interpretation of solar flare data observed by the UVSP (Ultraviolet Spectrometer and olarimeter), on-board the Solar Maximum Mission and the IRIS (Interface Region Imaging Spectrograph), and also to data from B2-SOLPS (Scrape Off Layer Plasma Simulations) for MAST (Mega Ampère Spherical Tokamak) Super-X divertor upgrade. The derived atomic data, calculated in the framework of the ADAS (Atomic Data and Analysis Structure) project, allow equivalent prediction in non-stationary transport regimes and transients of both the solar atmosphere and tokamak divertors, except that the tokamak evolution is about one thousand times faster.
