Applications are open for 1 (one) Research Studentship(s), within the framework of project Plasma Surface Interaction (Data and Tools) COupled Modelling (PSI.COM) of IPFN – PEP: 1801P.01261.1.01.01, reference 2022.04128.PTDC, financed by national funds through FCT/MCTES (PIDDAC

Workplan: The work addresses the modelling of N2-H2 plasmas with a description of the electron and the heavy-species kinetics in the plasma volume, the transport of species towards the wall and a description of the surface kinetics, accounting for the heterogeneous catalytic formation of ammonia at the wall.

Self-consistent simulations will use the LisbOn KInetics (LoKI) tool suite, coupling a Boltzmann solver (LoKI-B) and a Chemistry solver (LoKI-C), to obtain the electron energy distribution function and the densities of the most relevant heavy species with the plasma. LoKI will be further developed and consolidated, aiming the final release of a full time-dependent algorithm, a set of Machine Learning LoKI-tools for sensitivity analysis, and a LoKI-B web-version.

Results will be validated against experimental characterization and diagnostics of N2-H2 discharges (probe, optical/laser spectrometry, mass spectrometry measurements) performed at the Laboratoire de Physique des Plasmas (LPP), Paris, France.

Tentative goals are as follows:

- Update of the current N2-H2 Lisbon model (volume and surface), to improve its predictions

- Development and consolidation of the LoKI tool suite, aiming at full time-dependent description, and including Machine Learning tools for reduction of chemistry schemes

- Participation in the experimental characterization and diagnostics of the plasma, for model validation

This work plan and objectives can contribute to a Master's dissertation on the same subject.

Duration: The research fellowship(s) will have the duration of 6 months. It’s expected to begin in October 2024, and may be eventually renewed up to the maximum of 12 months, including the duration of the initial contract.
