The Relativistic Proton Spectrometer: A Review of Sensor Performance, Applications, and Science

Autor: J. E. Mazur, T. P. O’Brien, M. D. Looper

Publikováno v: Space Science Reviews. 219

The Relativistic Proton Spectrometer (RPS) on the Van Allen Probes spacecraft was a particle spectrometer designed to measure the flux, angular distribution, and energy spectrum of protons from $\sim60~\text{MeV}$ ∼ 60 MeV to $\sim2000~\text{MeV}$

Autor: Harlan E. Spence, Nathan A. Schwadron, Wouter de Wet, S. Smith, Fahad Zaman, M. D. Looper, Lawrence W. Townsend, Andrew P. Jordan, Jody K. Wilson

Publikováno v: Acta Astronautica. 175:185-189

When high energy galactic cosmic ray (GCR) particles collide with the lunar regolith, they eject “albedo” particles from the surface. The albedo particles could be either scattered incident ions, or secondary ions and neutrons produced by the col

The Magnetic Electron Ion Spectrometer: A Review of On-Orbit Sensor Performance, Data, Operations, and Science

Autor: Drew Turner, M. D. Looper, James L. Roeder, J. H. Clemmons, A. J. Boyd, Geoff Reeves, J. B. Blake, Christine Gabrielse, Seth G. Claudepierre, T. P. O'Brien, J. E. Mazur, J. F. Fennell, Harlan E. Spence

Publikováno v: Space Science Reviews

Measurements from NASA's Van Allen Probes have transformed our understanding of the dynamics of Earth's geomagnetically-trapped, charged particle radiation. The Van Allen Probes were equipped with the Magnetic Electron Ion Spectrometers (MagEIS) that
