Automated workflow for energetic particle stability — •Virgil - Alin Popa, Philipp Lauber, and Thomas Hayward-Schneider — Max Planck Institute for Plasma Physics, Garching, Germany

EPs (Energetic Particles) driven instabilities are a concern for present (AUG, JET) and future (ITER, DEMO) fusion devices. These particles can come from Neutral Beam Injection or be generated from fusion reactions (alpha particles). Their impact on electromagnetic instabilities in tokamak plasmas can lead to energetic particle transport which affects the heating efficiency of the plasma. Different codes that can study predictive scenarios and/or experimental results are emerging and with them the need of automatic analysis and management of the data they produce. In order to study the linear/non-linear, local/global effects, a workflow that manages the work of several codes is necessary and has been developed using the IMAS framework (Integrated Modelling & Analysis Suite). In addition, several techniques for reducing the dimensionality of the physics results have been implemented, such as: using statistical methods to improve analytical formulas and splitting of the workload in relevant/non-relevant data.
