Geometry effects on zonal flow dynamics and turbulent transport in optimized stellarators

Nuclear Fusion
Global gyrokinetic simulations find a strong suppression of ion temperature gradient (ITG) turbulence by zonal flows in stellarators optimized for neoclassical transport.

A perturbative multi-mode model with finite parallel electric field for fast-ion-driven Alfvén eigenmodes

Nuclear Fusion
Alfvén eigenmodes are of great interest in any fusion device as they can be excited by fast ions in the plasma. If the modes grow to large amplitudes, they can cause transport and redistribution of the fast ions, thus limiting fusion performance. To save

A new continuous optimization method of standardized cubic permanent magnets for stellarators

Nuclear Fusion
Stellarator configurations can be realized using permanent magnets in combination with tokamak-like planar coils. From the perspective of engineering feasibility and cost-effectiveness, using standardized cubic permanent magnets with a finite number of ...

Stellar ages and stellar rotation

, 2016
Stellar ages will play a big role in the next generation of astronomy. Useful to exoplaneteers and galactic archaeologists alike, this relatively under-exploited stellar property is currently limited by the precision of dating techniques. The work presented in this thesis contributes incrementally to a greater understanding of rotation period decay in ...
