Tearing mode simulations

Motivation

• Tearing instability can be affected by kinetic effects
• Gyrokinetic simulations of tearing instability is needed
• Challenge: coupling tearing mode and turbulence

Single tearing instability

Tearing instability in turbulent environment

Electrostatic potential (poloidal cross-section)
Electrostatic potential for toroidal mode number n=1
Electrostatic potential for toroidal mode number n=5
Evolution of toroidal spectrum (electrostatic potential)

Outlook
