Abstract
Variations of relativistic electron fluxes (E ≥ 1 MeV) and wave activity in the Earth magnetosphere are studied to determine the contribution of different acceleration mechanisms of the outer radiation belt electrons: ULF mechanism, VLF ...

Abstract
Using Arase observations of the inner magnetosphere during 26 CIR‐driven geomagnetic storms with minimum Sym‐H between ‐33 and ‐86 nT, we investigated ring current pressure development of ions (H+, He+, O+</sup...

ジオスペース探査衛星ERG(Energization and Radiation in Geospace)は,これまで集中的な直接観測が成されてこなかった放射線帯領域を含むジオスペースを観測し,この領域のもつ相対論的粒子の加速機構や宇宙嵐に伴うジオスペース変動の解明を行う.このERG衛星による粒子観測は,計6つの電子・イオン計測器を用いて行われ,その電子計測器の一つであるHEP-eは,0.07〜2MeVの電子をSSSD(Single-sided Silicon Strip Detector...
