Operational space of the ASDEX Upgrade tokamak and its proximity to that of future devices with burning plasma — •Daniela Kropáčková, Emiliano Fable, Ondřej Kudláček, Hartmut Zohm, and ASDEX Upgrade Team — Max-Planck-Institut für Plasmaphysik, Boltzmannstr. 2, Garching, D-85748, Germany
Present-day tokamaks are unable to capture the dynamic interaction between alpha heating and the plasma operational scenario during changing operating conditions as expected in future reactors. To enable these investigations, a method for emulating dominant alpha heating in existing tokamak experiments was introduced in [FableNF2023].
In this contribution, a database of operational scenarios of ASDEX Upgrade (AUG), covering ELM-free regimes such as EDA and QCE, scenarios with ELM suppression via resonant magnetic perturbations (RMPs), flux-pumping scenarios, and operation with a X-point radiator (XPR), is presented. The interesting operational space is characterized in terms of key non-dimensional parameters, e.g., νeff, βN, ρ*, and q95. These parameters are compared with the expected values for a few considered fusion reactors, and the conditions under which relevant physical parameters can be matched are identified.
The selected scenarios are then used to calibrate the alpha heating power proxy through simulations performed with the flight simulator Fenix. Experimental validation of the obtained results is planned for a future campaign, followed by burn control studies.
