AB: We present a systematic study of the diamagnetic cavities and adjacent regions in the vicinity of the high-altitude cusp. We are utilizing various Cluster spacecraft separations in order to identify the size and overal structure of these cavities and will compare with 3-D high-resolution MHD simulations. Our initial simulation results indicate that the diamagnetic cavities can play an important role in the particle acceleration, therefore it is important to understand their formation mechanism, overal dynamics and structure.
