This work aims at augmenting the ASTRA transport code capabilities of simulating magnetic confinement fusion devices. In parallel, two avenues are pursued:
First, a few options for a reduced, theory-based scrape-off-layer (SOL)/exhaust model will be explored and implemented to allow simulations of seeded discharges and discharges with both low and high-recycling regimes displaying either impurity flush-out or detachment. Application to ASDEX Upgrade and future devices like ITER and DEMO, where the FENIX flight simulator (to which ASTRA is coupled) is being deployed, is foreseen.
Second, the implementation of an equation for the current diffusion compatible with a vacuum helical field (as in a stellarator device) will be pursued. After which, the inclusion of reduced models for stellarator physics may be initiated. The goal is to develop a tool that can be used for both tokamak and stellarator-reduced modeling, paving the way for a flight simulator that can also simulate stellarators.
