Working Group 3: Gamma Rays and Ions

Working Group 3 delves into pivotal aspects of gamma rays and ions, focusing on the present state of analyses, imminent observations, and ongoing construction of crucial instruments. The discussions will encompass the key scientific questions in this domain, future analyses, and advancements in observational technologies. Collaborations include combined observations from RHESSI, Fermi, and future instruments like GRIPS. Various topics include gamma-ray production, ion acceleration signatures, and the role of neutrons and solar energetic particles, contributing to a comprehensive understanding of solar and heliospheric phenomena.
