Stellarator Evolution Modeling

January 17, 2023

We are proposing to work with PPPL to use new tools, which is expected to be available in early 2023, to understand the effect of bootstrap current on island growth in stellarator geometry. The tools are modifications to the PPPL flagship code M3D-C1 which is a time dependent resistive MHD code. The two planned changes are to add a “Sauter-like” model (valid only in quasi-symmetric configurations) and also interface to the SFINCS code by Landreman (U. Maryland) to M3D-C1. these tools will be benchmarked against each other and used to understand neoclassical island healing in stellarator-like magnetic shear.
