Discovery of proton hill in the phase space during interactions between ions and electromagnetic ion cyclotron waves

Abstract A study using Arase data gives the first observational evidence that the frequency drift of electromagnetic ion cyclotron (EMIC) waves is caused by cyclotron trapping. EMIC emissions play an important role in planetary magnetospheres, causing scattering loss of radiation belt relativistic e...
