Challenges for the EUSO Project — •Patricia Liebing and Masahiro Teshima — Max-Planck Institut für Physik, München

The EUSO space mission has been proposed to operate on the International Space Station (ISS) for at least three years starting in 2010. The primary goal of the project is the detection of UHECRs with energies above 5·10¹⁹ eV using the fluorescence light emitted in extended air showers (EAS) induced by them. By looking down onto the Earth’s atmosphere from the ISS with a field of view of 60^∘ the effective collection area is about a factor of 10 larger than that of the largest current ground based experiments.

A highly efficient photon detector is required in order to provide a relatively low threshold and overlap with the existing ground based experiments, to collect sufficient statistics of UHECRs and to precisely estimate their energy. The energy calibration will be affected by the presence of clouds and aerosols, therefore it is mandatory to monitor the atmosphere. The additional limitations on the weight, power consumption and mechanical stability of the instrument are challenging. In this report we will discuss the use of novel techniques and technologies that may fulfill the above mentioned requirements.
