英文摘要 | Energetic electron injections can generate or amplify electromagnetic waves such as whistler-mode waves. These waves can resonantly interact with available particles to affect their equatorial pitch angle. This process can be considered as a diffusion that scatters particles into the loss cone. This study investigates whistler-mode wave generation in conjunction with electron injections using in-situ wave measurements by the THEMIS mission during 2011-2020. We characterize the whistler-mode wave behavior associated with 733 selected dispersionless electron injections and Dipolarizing Flux Bundles (DFBs). We observe intense wave activity and strong diffusion associated with only the top 5 and 10% of the selected injection events respectively. We also study the wave activity when there is a sharp rise in the northward component of the magnetic field around the injection time (DFBs). In this case, the generated wave powers increase, and the power change is at least 2 times greater than non-DFB injections. |
