The effect of triangularity on tokamak boundary plasma turbulence is investigated using
global, flux-driven, three-dimensional, two-fluid simulations. The simulations show that …

One suggested benefit of long-leg, tightly baffled divertor configurations, a common feature
included in the designs of many next-generation fusion devices, is access to a delocalized …

Exhausting power from the hot fusion core to the plasma-facing components is one of the
biggest challenges in fusion energy. The MAST Upgrade tokamak uniquely integrates strong …

Tokamak à configuration variable (TCV), recently celebrating 30 years of near-continual
operation, continues in its missions to advance outstanding key physics and operational …

TCV's operating regime with an X-point radiator (XPR) has been broadened by changing the
magnetic geometry. XPRs have properties that could make them an attractive power exhaust …

Experimental data from NSTX and DIII-D discharges with the snowflake (SF) divertor
configurations are analyzed toward the development of the X-point radiator (XPR) concept …

In recent years, negative triangularity (NT) has emerged as a potential high-confinement L-
mode reactor solution. In this work, detachment is investigated using core density ramps in …

Edge-plasma simulations of a baffled, long-legged divertor in DIII-D, performed using the
multi-fluid code UEDGE, indicate that the position of the detachment front is constrained to …

In this dissertation, we investigate two proposed features aimed at improving the
performance of the divertor exhaust system in tokamak nuclear fusion devices. Specifically …
