 SWEAP

SWEAP consists of the Solar Probe Cup (SPC), a faraday cup which faces the Sun and is designed to measure electrons and ions in the space environment near the Sun; the Solar Probe Analyzers (SPAN-A and SPAN-B); and the SWEAP electronics module (SWEM).The Solar Probe Cup is a Sun facing instrument directly exposed to the Sun, and had to be designed to handle the high temperature conditions at 9-10 Solar radii from the Sun, that are planned for the mission.
