抄録（英）
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 near-ultraviolet wavelength region to observe time-resolved atmospheric fluorescence images of the extensive air showers from the International Space Station.
The focal surface is a spherical curved surface, and its area amounts to about 4.5 m2. The focal surface detector is covered with over 5,000 multi-anode photomultipliers (MAPMTs). The focal surface detector consists of Photo-Detector-Modules, each of which consists of 9 Elementary Cells (ECs). The EC contains 4 units of MAPMTs. Therefore, 1,300 ECs or about 150 PDMs are arranged on the whole of the focal surface of JEM-EUSO. The EC is a basic unit of the MAPMT support structure and the front-end electronics. The PDM is a basic unit of the focal surface structure and the data acquisition system.
