Welcome to the WIND 3-D Plasma and Energetic Particle Investigation home page. This experiment is designed to measure the full three-dimensional distribution of suprathermal electrons and ions at energies from a few eV to over several hundred keV on the WIND spacecraft. Its high sensitivity, wide dynamic range, and good energy and angular resolution make it especially capable of detecting and characterizing the numerous populations of particles that are present in interplanetary space at energies above the bulk of the solar wind particles and below the energies typical of most cosmic rays. The measurements can be used in conjunction with other particle, plasma wave, and magnetic field experiments on WIND to unravel the details of where these particles come from, how they are accelerated and transported, and what effects they have on the Earth's interplanetary space environment.
