We invite contributions to the session “Sources for Suprathermal Ions” (https://agu.confex.com/agu/2018tess/preliminaryview.cgi/Session40387)
at The Triennial Earth–Sun Summit that will be held on May 20-24, 2018 at the Lansdowne Resort and Spa in Leesburg, VA, USA (https://connect.agu.org/tess2018/home).

Session Description:
Suprathermal ions (ions of a few times the solar wind plasma energy up to 100s of keV per charge) are known to play a significant role as the seed population in the acceleration to high energy particles by coronal mass ejection (CME) shocks. In the quest for a reliable prediction of the properties of large solar energetic particle (SEP) events, one crucial element is a quantitative understanding of how the suprathermal particles are produced and distributed in the solar corona and the solar wind, especially as a sustained source. Another crucial element is a quantitative understanding of how the variation in the suprathermal seed population contributes to the variation in SEP properties. This session invites contributions from theories, models and observations that aim toward this aspect of research.

Session conveners: Yuan-Kuen Ko (yuan-kuen.ko@nrl.navy.mil), George C. Ho (George.Ho@jhuapl.edu), Nariaki Nitta (nitta@lmsal.com)

Abstract submission deadline: February 20, 2018

The Triennial Earth-Sun Summit (TESS) is a joint meeting of the Space Physics and Aeronomy Section of the American Geophysical Union (AGU) and the Solar Physics Division (SPD) of the American Astronomical Society.
