An innovative techinque for detecting solar and galactic radiations with an isotropic sensor by the ramsess cubesat mission

Space missions, in Low Earth Orbit (LEO), outside of the Earth’s magnetosphere are critical because of space radiation, including the high-energy particles of the Sun i.e., trapped protons and electrons of the inner and outer Van Allen Belts which are dangerous for the electronics of the spacecraft and/or a manned crew. This paper deals with the ongoing development of RAMSESS (RAdiation Measurement Sensor with Enhanced Sensibility for Space exploration), a 6U-CubeSat project funded by the Italian Space Agency (ASI) in the framework of the national program Space 19/ALCOR. The main aim of the Cubesat mission is the validation in a relevant radiative environment of the payload, an innovative semiconductor-based (i.e., CdZnTe, hereinafter CZT) dosimeter through the characterization of the radiation environment in low-Earth polar orbit, near the outer Van Allen Belts.
