Non-local neoclassical PIC simulations for the self-consistent radial electric field in stellarators. — •Michał Kuczyński, Ralf Kleiber, and Håkan Smith — Wendelsteinstraße 1, 17491 Greifswald, Germany

Transport in fusion plasma devices can be classified as either turbulent or neoclassical. Since turbulent transport is predominantly ambipolar, the radial electric field that arises ensures ambipolarity of the neoclassical part of the transport. This fact allows us to perform neoclassical particle-in-cell (PIC) simulations to calculate the electric field self-consistently. We introduce non-linear and non-local terms into the equations of motion in order to investigate ion and electron root transitions.
