Van Allen Probe A, Relativistic Proton Spectrometer, RPS, Proton Spectrometer Belt Research, PSBR, Data. The RPS Instrument is a Solid State Detector Telescope combined with a Cherenkov Radiator. It measures Protons with Energies from about 60 MeV to about 2 GeV. For more Information, see http://rbsp.aerospace.org/. For a complete Description of the Instrument, see Mazur et al., 2012, The Relativistic Proton Spectrometer (RPS) for the Van Allen Probes Mission (formerly known as Radiation Belt Storm Probes, RBSP), Space Science Reviews. DOI 10.1007/s11214-012-9926-9, http://www.springerlink.com/content/p84680786570g7qp/. The instrument PI, Joseph Mazur, can be reached at Joseph.E.Mazur@aero.org.

J. Mazur. The Aerospace Corporation designed and built the RPS Instrument with Funding from The National Reconnaissance Office. The RPS Principal Investigator is Joseph Mazur. Those wishing to use RPS Data are strongly urged to notify the Principal Investigator concerning the Topic of their Work. This will enable the RPS Team to assist in Use of the Data and to track the Utility of the Instrument to the broader Community.
