MIOS (Millimetre-wave Instrument for the Observation of the Sun) is a full solar disk radiometer operating at 90GHz, purposely designed to detect radio emission from MeV-energy electrons in solar flares. MIOS is one of the two baseline instruments of the ADAHELI (ADvanced Astronomy for HELIophysics) mission, whose feasibility study has been successfully completed in December 2008. The other baseline instrument is ISODY, an optical telescope equipped with two coupled Fabry-Perot interferometers for high-resolution spectroscopy in the Near-Infrared. ADAHELI is a 500kg Satellite, planned to be placed on a helio-synchronous orbit (800 km height) in order to have continuous Sun pointing during its three years lifetime. ADAHELI phase A has been funded by the Italian Space Agency (ASI) in the framework of its "Small Missions" program. MIOS will study the Sun with high time-on-target, high temporal resolution and good sensitivity. The main goal is to obtain a large sample of millimeter flare detections in order to address several outstanding scientific questions regarding particle acceleration and transport in the corona. MIOS will also be used to study the relationship between flares and coronal mass ejections, the latter having effects on Space Weather and near-Earth conditions.

Abstract
MIOS (Millimetre-wave Instrument for the Observation of the Sun) is a full solar disk radiometer operating at 90GHz, purposely designed to detect radio emission from MeV-energy electrons in solar flares. MIOS is one of the two baseline instruments of the ADAHELI (ADvanced Astronomy for HELIophysics) mission, whose feasibility study has been successfully completed in December 2008. The other baseline instrument is ISODY, an optical telescope equipped with two coupled Fabry-Perot interferometers for high-resolution spectroscopy in the Near-Infrared. ADAHELI is a 500kg Satellite, planned to be placed on a helio-synchronous orbit (800 km height) in order to have continuous Sun pointing during its three years lifetime. ADAHELI phase A has been funded by the Italian Space Agency (ASI) in the framework of its "Small Missions" program. MIOS will study the Sun with high time-on-target, high temporal resolution and good sensitivity. The main goal is to obtain a large sample of millimeter flare detections in order to address several outstanding scientific questions regarding particle acceleration and transport in the corona.
