Observation of electron pitch angle distribution in Saturn's inner magnetosphere

Abstract

The Magnetospheric Imaging Instrument (MIMI) onboard the Cassini spacecraft has observed energetic particles in Saturn's magnetosphere. In order to clarify energetic particle distribution, we have investigated pitch angle distributions of 20 keV – a few MeV electrons in the inner magnetosphere (<15 Rs). In this presentation, we will discuss the effect of absorption by the E-ring and the possibility of wave-particle interactions based on the Radio and Plasma Wave Science (RPWS) data.
