/ Abstract
Galactic cosmic rays and solar energetic particles (SEPs) affect the performance of instruments carried on board space missions and are the source of the absorbed dose to astronauts. Particles above 100 MeV are the most penetrating. The overall particle flux impacting spacecraft increases by several orders of magnitude during the most intense SEP events and gamma-ray bursts, compared to the galactic cosmic-ray background. Unfortunately, most detectors dedicated to the monitoring of solar particles in space do not allow measurements above 200 MeV. Space agencies and the space and heliospheric weather communities are interested in improving this scenario. We propose a new, compact, low-power, and radiation-resistant instrument, intended for long-duration missions to monitor solar X-rays, electrons, and protons up to energies of tens of keV, MeV, and 600 MeV, respectively. Intense long and short gamma-ray bursts would be observed in the absence of solar activity.
