Abstract: The Extreme Universe Space Observatory (EUSO) on the International Space Station (ISS) will detect the Ultra High Energy Cosmic Rays (UHECRs with E > 4 ×1019 eV) and the high energy cosmic neutrino flux looking at the streak of fluorescence light produced when the particles interact with the Earth’s atmosphere. The photo-detector of EUSO experiment will consist of several Multi-Anode PhotoMultipliers (MAPMTs) arranged on the aspheric focal surface. Accurate pre-flight ground calibration and in-flight calibration are essential topics of the EUSO experiment to detect reliably the fluorescence light. In particular, the main target of calibration is to achieve spectroradiometric measurements
of the telescope performance and of the absolute response of the detectors. This report will describe a first approach to, and some possible solutions for, the calibration system of the EUSO telescope and focal plane. This proposal will address the requirements to design the EUSO calibration system and the crucial items for further analyses and discussions.
