DESCRIPTION:" Gyrokinetic analysis of microinstability-driven dynamics in a
  QSH environment on the Madison Symmetric Torus" by Matt Stowe\,\nmentor Za
 ch Williams\, \n2024 Summer Research\n\nReversed-Field Pinches operating in
  Quasi-Single-Helicity (QSH) geometry exhibit significantly improved confin
 ement time compared to standard discharges due to efficient saturation of l
 arge scale tearing modes. However\, this modified geometry introduces new i
 nstabilities that can drive transport as well as high-frequency parallel ma
 gnetic field fluctuations\, which have been directly observed in experiment
 s. This work focuses on categorizing these fluctuations through computation
 al analysis of the microinstabilities and microturbulence present in a non-
 reversed Madison Symmetric Torus QSH experiment. Local gyrokinetic simulati
 ons are conducted using the new GENE 3.0 code to advance existing studies t
 hat identified ion-temperature-gradient and trapped-electron-mode instabili
 ties present in the core and edge regions of the device respectively. Micro
 instability-driven transport is thoroughly categorized and discussed\, with
  particular attention given to the role of zonal flows and sensitivity to t
 earing-mode-like fluctuations. Parallel magnetic field fluctuations are als
 o included in the simulations for more direct comparison to experimental da
 ta.
