SAMPEX Data Pages

The data on this site are only for the use of SAMPEX investigators, to distribute preliminary results of analyses of spacecraft attitude, instrument modes, and science data. In particular, a lot of the data shown on this site contain known instrumental and operational-mode artifacts which have been corrected for incompletely or not at all. So caveat lector!

• PET Geometry and Response: dimensions and electron/ion response of PET (new 17 September 2007).
• Some Space Physics Jargon: definitions of a few space physics terms (new 24 November 2004).
• Electron interaction with atmosphere: Results of EGSnrc Monte Carlo simulations of electrons interacting with the Earth's upper atmosphere (new 1 October 2003).
• Drift loss-cone: Graphical description of the concept of the drift loss cone, which we have found to be useful in separating transient injections of particles from the steady, and often overwhelming, background level of the radiation belts (new 9 October 2000).
• Correction factors for PEN PHA events: Plots of fraction of PEN events with no guard triggers, showing the varying magnitude of the correction needed for fluxes derived during periods with inconsistent handling of particle events by rate scalers and PHA buffers (new 27 May 2000).
• Effectiveness of pointing strategies: Plots of fraction of time spent looking at different pitch angles, showing effects of revisions to pointing algorithm (new 4 March 2000).
• PET coincidence logic: Graphical representations of the PET detector coincidence conditions defining the P, E, RNG, and PEN buffers and rates, showing variations over the SAMPEX mission (new 6 August 1999, revised 7 January 2000).
• Pitch-angle comparisons: Plots of SAMPEX data orbit by orbit, showing the effects on the measured flux due to variations in the pitch angle seen by the instruments on different orbits and different parts of a single orbit (new 21 April 1999, revised 13 September 1999).
• Attitude movies: Animated GIF files of the attitude variations of the SAMPEX spacecraft as it orbits Earth, including changes in this behavior under the various attitude-control modes (new 9 March 1999).
