Overall view of the JEM-EUSO instruments

Abstract

JEM-EUSO mission with a large and wide-angle telescope mounted on ISS has been planned to open up "particle astronomy" through the investigation of extreme-energy cosmic rays by detecting fluorescent and Cherenkov photons by air showers developed in the earth's atmosphere. The JEM-EUSO telescope consists of optical Fresnel lenses with a diameter of about 2.5 m, 300 k channels of MAPMT, frontend readout electronics, trigger electronics, and system electronics. An infrared camera and a LIDAR system will be used to monitor the earth's atmosphere. © 2011 American Institute of Physics.
