Describe and understand the effect of topologic features (e.g. islands, different curvature and connection lengths, etc.) to filament characteristics. | Strong difference in magnetic curvature has a strong impact on interchange force and so potentially in the blob dynamics [D. Carralero et al. Phys. Rev. Lett. 115.21 215002 (2015)]. | ||
TJ-II is equipped with a dual system of multi-probes arrays placed at two different toroidal and poloidal locations [probes B and D] [T. Kobayashi, U. Losada, B. Liu et al., Nuclear Fusion 59, 044006 (2019)]. While probe B lies in a neutral to favorable curvature probe D is in an unfavorable negative curvature zone. This makes TJ-II a unique device to explore (simultaneously) the influence of magnetic curvature on blob dynamics. | |||
The goal of this research proposal is: | |||
1. Characterize filaments and evaluate filament propagation models, already tested in tokamaks. | |||
2. Describe and understand the effect of topologic features (e.g. islands, different curvature and connection lengths, etc.) to filament characteristics. | |||
