ICTP 2024

Data for Modelling Atomic and Molecular Processes in Plasmas

This joint IAEA-ICTP Workshop was a 5-day series of lectures and computing practical exercises to help early-career plasma physicists develop an understanding of the techniques used to model and simulate the radiative and collisional properties of plasmas. The topics chosen are those relevant to the modelling and spectroscopic analysis of plasmas at the atomic level with applications to fusion, astrophysics and industry. Where relevant, the rapidly enlarging field of Artificial Intelligence were related to the topics covered, with practical examples and exercises supporting the lectures and demonstrations.

The School was held in the Kastler lecture hall at the ICTP, near Trieste, from 18 – 22 March 2024. Further details and are available on the ICTP website.
