Wind Solar Wind Experiment (SWE) Faraday Cup, Solar Wind Plasma Reduced Ion Distribution Functions, 92 s Data

Published by SPDF | National Aeronautics and Space Administration | Catalog Last Checked: September 23, 2026 at 12:09 AM | Dataset Last Updated: September 22, 2026
WIND Solar Wind Experiment, SWE, Faraday cup data: this data set contains three-dimensional measurements of ions in the energy range 150 eV to 8 keV. Placed 15° above and below equatorial plane of the spacecraft, the Faraday Cups measure ion charge flux as a function of epoch, cup number, orientation angle, and bias grid potential. For each time point, a full spectrum is comprised of charge flux measurements at the two Faraday cup sensors at 20 azimuth angles for each of 31 energy-per-charge windows with 1240 data points per spectrum. Spectra are built up over approximately 92 s intervals. The effective area of the Faraday cup sensor as a function of incidence angle onto the cup is also provided.
