Gyrokinetic simulations of magnetic reconnection in weakly collisional plasmas are presented. A two-dimensional gyrokinetic particle-in-cell (2D-gyroPIC) model, tailored to the experimental conditions of the VINETA-II linear device, is employed to investigate the physics of fast reconnection. The evolutions of fields and particle distribution functions are studied as functions of reconnection drive, inhomogenity effects, and the ratio of parallel to perpendicular magnetic fields relative the induced current sheet. Key objectives of the work include electron and ion drift motions and the role of fluctuations on reconnection in low-collisionality systems.
