The Solar-Wind Plasma Experiment for International Solar Polar Mission (ISPM) will accurately characterize the bulk flow and internal state conditions of the interplanetary plasma in three dimensions at all heliocentric distances and heliographic latitudes reached by the spacecraft. Solar-wind electrons, protons, alpha particles, and heavier ions will be measured routinely. The heavy ions will also be measured less frequently in a higher sensitivity instrument configuration. Under favorable conditions, ions of oxygen, silicon, and iron at various charge levels will be resolved. Electrons and ions will be measured simultaneously with independent curved-plate electrostatic analyzers equipped with multiple continuous Channel Electron Multipliers (CEMs). The CEMs are arranged so that particle velocity distributions are suitably resolved without gaps in spacecraft polar-angle space.
