SUMMARY:Effects of magnetic geometry and neutrals in gyrokinetic simul
 ations of magnetized boundary plasmas\, Plasma Physics (Physics/ECE/NE
  922) Seminar\, Dr. Tess Bernard\, General Atomics
DESCRIPTION:Successful fusion pilot plant (FPP) design hinges upon the
  ability to predict and control exhaust conditions to maximize the lif
 etime of plasma-facing components. This work describes a pathway towar
 d high-fidelity\, first-principles simulations with predictive capabil
 ities for plasma particle fueling and detachment. It presents the coup
 ling of a continuum full-f gyrokinetic turbulence model with atomic ne
 utral models\, using the Gkeyll code. To investigate how neutral inter
 actions and plasma shaping fundamentally affect edge turbulent transpo
 rt\, we carry out simulations of DIII-D inner-wall-limited (IWL) plasm
 as. We specifically consider negative triangularity (NT) plasmas\, whi
 ch exhibit robust confinement properties without the presence of disru
 ptive edge localized modes (ELMs). Results demonstrate good agreement 
 with experimental data\, with neutral interactions providing important
  particle fueling and heat loss channels. Our analysis reveals key dif
 ferences in the shear flow and turbulent fluctuations that contribute 
 to improved confinement properties in NT.
