FROM THE EXTREME UNIVERSE SPACE OBSERVATORY (EUSO) TO THE EXTREME ENERGY NEUTRINO OBSERVATORY

摘要

The fluorescence light duo tu the Cosmic Rays of Extreme) Euergyshow-oring in a huge mass of atmosphere, up to 2-3 * 10~(14) t, can be registered from a Low Earth Orbit (LEO: 400-1000 km of altitude). Using this technique a now field of fundamental research in Cosmology andin Aslroparlide Physics can be explored.The physios of Cosmic Hays of Extreme Energy willbe deeply investigated by the next generation of space detectors (EUSO, KLYPVE,..). For the Extreme Energy neutrino luitronomy such detectorHwill probably exhibit a lack of statistics and a further incron.se ofsonsitivity will be necessary for this) goal. The full coverage of tho whole observable air moan from a LEO requires to cover a Field of View (FOV) of 130°-140° by composing separate modules, each covering a smaller FOV. Tho ISS is the most suitable vehicle where those modules could bo Installed, or could be as Hempled in a co-llying complex. The ISS location also opens the possibility of a gradual realization of the full coverage, and a "technically evolving" approach: the optical system could be regarded as n. permanent facility on board (or co-llying with) the ISS for observing the Earth surface in optical and near-optical wavelengths and dill'oront sensors could bu alternated on its focal plane to meet the needH of dillerent experiments or services.The missions currently under study can be tho starting pieces for al'ull coverage facility.
