In recent years, the importance of wave-particle interactions with electrons on the dynamics of the radiation belt at Saturn has been increasingly apparent. Thanks to the wave surveys processed from the NASA Cassini mission we are now able to work out the combined effect of the interactions of different waves with the electron population in the inner magnetosphere. In this presentation we investigate how the acceleration and scattering we expect from individual wave types are affected by combining the individual wave effects. Z-mode, whistler mode chorus and hiss and have all been shown to accelerate electrons whilst ion cyclotron waves scatter them into the atmosphere. However, the strength and location of all these waves vary greatly and their impact on the electron population depends on the underlying plasma properties at any given location. We present our analysis of the effects of combinations of whistler-mode chorus and hiss, Z-mode and ion cyclotron waves on energetic electrons across the inner magnetosphere of Saturn.
