The gyrokinetic particle model of an magnetized plasma allows one to describe low-frequency phenomena with computation time much shorter than the ordinary particle model, and with accuracy higher than the drift-kinetic model. The gyrokinetic model has been used from microscopic to macroscopic phenomena, however, a simple gyrokinetic model is not suitable for the case of reflecting boundaries, because the guiding-center models, including gyrokinetic and drift-kinetic model, have a problem when the particles are reflected on the boundary, especially when the magnetic lines of force obliquely incident on the boundary. These conditions are essential in peripheral plasmas and divertor plasmas.
