Journal ArticleDOI
Rapid local acceleration of relativistic radiation-belt electrons by magnetospheric chorus
Richard M. Thorne,Wen Li,Binbin Ni,Qianli Ma,Jacob Bortnik,Lunjin Chen,Daniel N. Baker,Harlan E. Spence,Geoffrey D. Reeves,Michael G. Henderson,Craig Kletzing,William S. Kurth,George Hospodarsky,J. B. Blake,Joseph F. Fennell,Seth G. Claudepierre,Shrikanth Kanekal +16 more
TL;DR: High-resolution electron observations obtained during the 9 October storm are reported and chorus scattering explains the temporal evolution of both the energy and angular distribution of the observed relativistic electron flux increase, and detailed modelling demonstrates the remarkable efficiency of wave acceleration in the Earth's outer radiation belt.
Journal ArticleDOI
The Magnetic Electron Ion Spectrometer (MagEIS) Instruments Aboard the Radiation Belt Storm Probes (RBSP) Spacecraft
J. B. Blake,P. Carranza,Seth G. Claudepierre,J. H. Clemmons,W. R. Crain,Y. Dotan,J. F. Fennell,F. Fuentes,R. Galvan,J. S. George,Michael G. Henderson,M. Lalic,A. Y. Lin,M. D. Looper,D. J. Mabry,J. E. Mazur,B. McCarthy,C. Q. Nguyen,T. P. O'Brien,M. A. Perez,M. Redding,James L. Roeder,D. Salvaggio,G. A. Sorensen,Harlan E. Spence,S. Yi,M. Zakrzewski +26 more
TL;DR: In this paper, the authors describe the Magnetic Electron Ion Spectrometer (MagEIS) instruments aboard the RBSP spacecraft from an instrumentation and engineering point of view, including four magnetic spectrometers.
Journal ArticleDOI
Electron Acceleration in the Heart of the Van Allen Radiation Belts
Geoffrey D. Reeves,Harlan E. Spence,Michael G. Henderson,Steven K. Morley,R. H. W. Friedel,Herbert O. Funsten,Daniel N. Baker,Shrikanth Kanekal,J. B. Blake,J. F. Fennell,Seth G. Claudepierre,Richard M. Thorne,Drew Turner,Craig Kletzing,William S. Kurth,Brian A. Larsen,J. T. Niehof +16 more
TL;DR: Measurements from NASA’s Van Allen Radiation Belt Storm Probes are reported that clearly distinguish between the two types of acceleration, and the observed radial profiles of phase space density are characteristic of local acceleration in the heart of the radiation belts and are inconsistent with a predominantly radial acceleration process.
Journal ArticleDOI

Freeman,M. Maple,C. Nunez,T. Taylor,W. Toczynski,C. Urdiales,Harlan E. Spence,J. A. Cravens,L. L. Suther,Jie Chen +34 more
TL;DR: The HOPE mass spectrometer of the Radiation Belt Storm Probes (RBSP) mission is designed to measure the in situ plasma ion and electron fluxes over 4π sr at each RBSP spacecraft within the terrestrial radiation belts.
