M. Ricci, F. Kajino, T. Ebisuzaki  The Extreme Universe Space
Observatory on JEM/EF (JEM-EUSO) is a space mission to study
extremely high-energy cosmic rays. The JEM-EUSO instrument is a
wide-angle refractive telescope in the near-ultraviolet
wavelength region which will be mounted to the International
Space Station. Its goal is to measure time-resolved fluorescence
images of extensive air showers in the atmosphere. In this paper
we describe in detail the main features and technological
aspects of the focal surface of the instrument. The JEM-EUSO
focal surface is a spherically curved surface, with an area of
about 4.5 m2. The focal surface detector is made of more than
5000 multi-anode photomultipliers (MAPMTs). Current baseline is
