Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Sagamihara, Kanagawa Japan 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 timeresolved atmospheric fluorescence images of the extensive air showers from the International Space Station. In this paper we describe in details the main features and technological aspects of the focal surface of the instrument. The JEM-EUSO focal surface is a spherical curved surface, with an area of about 4.5m2. The focal surface detector is made of more than 5,000 multi-anode photomultipliers (MAPMTs). Current baseline is Hamamatsu R11265-03-M64. The approach to the focal surface detector is highly modular. Photo-Detector-Modules (PDM) are the basic units that drive the mechanical structure and data acquisition. Each PDM consists of 9 Elementary Cells (ECs). The EC, which is the basic unit of the MAPMT support structure and of the front-end electronics, contains 4 units of MAPMTs. In total, about 1,300 ECs or about 150 PDMs are arranged on the whole of the focal surface of JEM-EUSO. 形態: カラー図版あり 形態: CD-ROM1枚 Physical characteristics: Original contains color illustrations Note: One CD-ROM 資料番号: AA0065426122 宇宙航空研究開発機構宇宙科学研究所 Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS) 2011 eng conference output https://jaxa.repo.nii.ac.jp/records/10311 http://www.isas.jaxa.jp/j/researchers/symp/sss11/sss11_proc.shtml http://www.isas.jaxa.jp/j/researchers/symp/sss11/sss11_proc.shtml 第11回宇宙科学シンポジウム: 講演集録 Proceedings of the 11th Space Science Symposium 11
