Summary
Lots of different types of waves
the main ones that might come up during the week in breakout sessions highlighted here (with a weighting towards radiation belts!)
Relevance: waves can interact with particle populations in the magnetosphere
acceleration and loss mechanisms for various particle populations (e.g. radiation belts, ring current)
provide a way to transfer energy between different particle populations
