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
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
- 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
- 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
- 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).
