Effect of temperature anisotropy on the dynamics of geodesic acoustic modes
J. N. Sama, A. Biancalani, A. Bottino +7
In this work, we revisit the linear gyro-kinetic theory of geodesic acoustic modes (GAMs) and derive a general dispersion relation for an arbitrary equilibrium distribution functio…
Linear kinetic effects of core plasma on low frequency Alfven and acoustic eigenmodes in tokamaks
Ilija Chavdarovski, Fulvio Zonca, Liu Chen
The resonant and non-resonant effects of core plasma on the excitation of low frequency modes with , such as Beta-induced Alfvén Acoustic Eigenmodes (BAAEs) and Kinetic…
Complex space Newton-Raphson solution of the dispersion relation of low frequency Alfven waves in fusion plasmas
Ilija Chavdarovski
Newton-Raphson method in complex space is used to numerically solve the transcendental dispersion relation of low frequency shear Alfven waves in fusion plasmas. The equation exhib…
Saturation of energetic-particle-driven geodesic acoustic modes due to wave-particle nonlinearity
A. Biancalani, I. Chavdarovski, Z. Qiu +6
The nonlinear dynamics of energetic-particle (EP) driven geodesic acoustic modes (EGAM) is investigated here. A numerical analysis with the global gyrokinetic particle-in-cell code…
Turbulent Contributions to Ohm's Law in Axisymmetric Magnetized Plasmas
Ilija Chavdarovski, Renato Gatto
The effect of magnetic turbulence in shaping the current density in axisymmetric magnetized plasma is analyzed using a turbulent extension of Ohm's law derived from the self-consis…
On Zero Frequency Zonal Flow and Second Harmonic Generation by Finite Amplitude Energetic Particle Induced Geodesic Acoustic Mode
Zhiyong Qiu, Ilija Chavdarovski, Alessandro Biancalani +1
Nonlinear self-interaction of finite amplitude energetic particle induced geodesic acoustic mode (EGAM) is investigated using nonlinear gyrokinetic theory. It is found that both ze…
