Gyrokinetic simulation of the collisional micro-tearing mode instability

An application of recently developed perturbative particle simulation scheme for finite-$\beta$ plasmas in the presence of background inhomogeneities is presented. Originally [1], using similar scheme, we were able to simulate shear-Alfven waves, finite-$\beta$ modified drift waves and ion temperature gradient modes using a simple gyrokinetic particle code based on realistic fusion plasma parameters. Recently, we have successfully used the scheme for simulation of linear tearing and drift-tearing modes, in both collisionless semi-collisional regimes in slab geometry with sheared magnetic field. Here, we present further development of this scheme for the simulation of linear semi-collisional micro-tearing mode driven by electron temperature gradient [2] in high-aspect ratio cylindrical cross-section tokamak using the modified turbulence code GTS. \\[4pt] [1] E.
