Description:
The Charge Detector (CHD) of the Calorimetric Electron Telescope (CALET) onboard the International Space Station (ISS) has a huge geometric factor for detecting MeV electrons, and is sensitive to relativistic electron precipitation (REP) events. During the first four months, CALET CHD observed REP events mainly at the dusk to midnight sector near the plasmapause, where the trapped radiation belt electrons can be efficiently scattered by electromagnetic ion cyclotron (EMIC) waves. Here we show that interesting 5-20 s periodicity regularly exists during the REP events at ISS, which is useful to diagnose the wave-particle interactions associated with the non-linear wave growth of EMIC-triggered emissions.
