Gamma-ray, neutron, and hard X-ray studies and requirements for a high-energy solar physics facility

Abstract

The requirements for future high-resolution spatial, spectral, and temporal observations of hard X-rays, gamma rays and neutrons from solar flares are discussed in the context of current high-energy flare observations. There is much promise from these observations for achieving a deep understanding of processes of energy release, particle acceleration and particle transport in a complicated environment such as the turbulent and highly magnetized atmosphere of the active Sun.
