Working Group 3 Gamma Rays and Ions Leader

Working Group 3: Gamma Rays and Ions Leader: Albert Y. Shih Co-Leader: Alec Mac. Kinnon

Discussion focuses • The present – Ongoing analyses – Imminent observations – Instruments under construction • What are the important science questions? – Future analyses and observations – Future instruments

Monday Tuesday Wednesday 9 am Neutrons and SEPs / Albedo Nothing scheduled 11 am ENAs / Combined observations with RHESSI, Fermi, … Ion acceleration (joint with WG 6) 2 pm Signatures of ion acceleration RHESSI gamma-ray performance and analysis 4 pm Abundances in the solar atmosphere X-ray footpoints (joint with WG 2)

Signatures of ion acceleration • Ron Murphy – Gamma-ray production • Wei Chen – Gamma-ray spectroscopy of the 2005 Jan 20 flare • Gerry Share – Accelerated composition

Abundances in the solar atmosphere • Procheta Mallik – Low-FIP enhancement from Alfven ionization • Gerry Share – Ambient Ne/O ratio

Neutrons and SEPs / Albedo • Ron Murphy – Low-energy neutrons in the inner heliosphere • Neus Agueda – Search for heliospheric protons from low-energy neutrons • Gerry Share – Neutrons from the 2007 Dec 31 flare? • David Smith • Albert Shih

ENAs / Combined observations using RHESSI, Fermi, and beyond • Hugh Hudson – ENAs • Gerry Share / Michael Briggs – Observations of the 2010 Jun 12 flare • Albert Shih – GRIPS

RHESSI gamma-ray performance and analysis • • New DRM Artifact correction OSPEX additions Fermi/GBM data in OSPEX
