In Situ Measurements in the Auroral Plasma
In this chapter, we turn our attention to observations of the plasma physical processes occurring within the auroral acceleration regions. This includes acceleration processes: electric field formation, particle acceleration; dissipation processes: wave-particle interactions, wave growth, radiation; and energy transfer processes: magnetospheric/ionospheric coupling, Alfvén waves. In Chapter 2, we summarized the visible manifestations of these processes; here, using the theoretical tools provided in Chapter 3, we study the underlying plasma physics.
