Solar neutrons : scientific relevance and instrumentation for future missions in the inner heliosphere
The detection and the characterization of solar neutrons in the 1-20 MeV range remain among the key challenges for future research in solar physics. Measured during solar flares, those neutrons will provide unique information on timing, anisotropy and spectrum of accelerated protons and ions in the low corona. In addition, the detection of the quiescent component of the solar neutron flux also has a great discovery potential, in particular to understand the mechanisms heating the solar corona. After discussing the scientific interests and the requirements related to solar neutron detection, I will present the current status of the instrumentation developed for the preparation of prospective ESA / NASA missions into the inner heliosphere.
