1 Symposium on Planetary Science 213 Wave-Particle Interaction Analyzer: Direct Measurements of Wave-Particle Interactions in the Jovian Inner Magnetosphere Yuto Katoh [1] and Hirotsugu Kojima [2] [1] Department of Geophysics, Graduate School of Science, Tohoku University [2] Research Institute for Sustainable Humanosphere, Kyoto University Abstract: We present a new instrumentation "Wave Particle Interaction Analyzer (WPIA)" for measurement of the energy transfer process between energetic electrons and plasma waves in the magnetosphere. The WPIA measures a relative phase angle between the wave vector and velocity vector of each particle and computes an inner product W(t), while W(t) is equivalent to the variation of the kinetic energy of energetic electrons interacting with plasma waves [Katoh et al., 213]. The WPIA will be firstly realized by the Software-type WPIA in the ERG satellite mission to measure interactions between energetic electrons and whistler-mode chorus in the Earth's inner magnetosphere. In this talk we discuss scientific objectives of the WPIA in the Jovian inner magnetosphere and propose a possible plan of implementation for direct measurements of wave-particle interactions.
