The linear stability properties of the microtearing mode are investigated in the edge and core
regimes of the National Spherical Torus Experiment (NSTX) using the particle-in-cell method …

The magnetic drift and the electric potential play an important role in microtearing
destabilization by increasing the growth rate of this instability in the presence of collisions …

The performance of spherical tokamak reactors depends on plasma β, and an upper limit is
set by long-wavelength kinetic ballooning modes (KBMs). We examine how these modes …

Collisionless microtearing modes have recently been found linearly unstable in sharp
temperature gradient regions of large aspect ratio tokamaks. The magnetic drift resonance of …

In this work, linear and nonlinear collisionless electrostatic simulation studies of the standard
and short wavelength ion temperature gradient mode (SWITG) for experimental profiles and …

Nonlinear simulations are carried out for the microtearing mode using particle-based δ f
gyrokinetic simulations for parameters relevant to spherical tokamaks. The present study …

The electromagnetic effect is studied on the short wavelength branch of the ion temperature
gradient mode in the linear regime for the first time using a global gyrokinetic model. The …

In H-mode plasmas, the modeling of the pedestal dynamics is an important issue to predict
temperature and density profiles in the tokamak edge and therefore in the core. The EPED …

An investigation on the onset of low n kinetic ballooning mode (KBM) in a plasma
environment relevant to the spherical reactors is carried out. The low n modes can be quite …
