Wave Particle interactions in the magnetosphere, a charged particle perspective: Observations, Instrumentation and Mission Concepts

It is well known that the terrestrial magnetosphere contains natural emissions in the form of plasma waves ranging from broad band emissions (e.g., plasmaspheric hiss) to discrete emissions (e.g., Electromagnetic Ion Cyclotron-EMIC-waves). These may be excited by external stimuli such as solarwind structures or terrrestrial source such as lightning [Helliwell, 1969]. Theses plasma waves interact with charged particles in the magnetospheric radiation belts causing these particles to be energized or loss by precipitation into the atmosphere (for reviews see Kanekal and Miyoshi 2021; Millan and Thorne, 2007; Thorne 2010).
