Description

The Solar Probe Plus (SPP) mission will launch in 2018 and fly to within nine solar radii of the surface of the Sun. One of the prime scientific objectives for SPP is to explore the dynamics of energetic particles, and the two instruments of the Integrated Science Investigation of the Sun (IS0IS) will make the key measurements for this objective. In concert with the other SPP instruments, the IS0IS observations will allow us to explore the energetic particle origins, acceleration, and transport. The IS0IS low-energy Energetic Particle Instrument (EPI-Lo) measures ions and ion composition from ~20 keV/nucleon to 15 MeV total energy and electrons from ~25 – 1000 keV with nearly a 2π field-of-view. The high-energy Energetic Particle Instrument (EPI-Hi) for IS0IS analyzes the composition and energy spectra of protons through nickel from ~1 – 200 MeV/nucleon and electrons between approximately 500 keV and 6 MeV. These unique observations on SPP will add a crucial new perspective on the discovery, untangling, and understanding of physical processes within 0.3 AU where solar energetic particles are accelerated to the highest energies.
