Abstract

The primary scientific objective of the Solar WindProton and Alpha Sensor (SW-PAS) for the Solar Orbiter (SO) mission is to provide observations of kinetic and fluid properties of the bulk solar wind plasma that will ultimately lead to new discoveries and improved understanding of coronal heating, the origin and acceleration of the solar wind, and the seed population of solar proton events. Specifically, the SW-PAS will measure the 3-D velocity distribution functions of solar wind and suprathermal protons and α-particles between 200 eV/q-20 keV/q energy range at high temporal resolution. In this paper, we outline the main scientific goals, instrument concept, and critical issues required for the design and development of the SW-PAS sensor.
