Abstract content

JEM-EUSO with a large and wide-angle telescope mounted on ISS has been planed as a space mission to explore extremes of the universe through the investigation of ultra-high-energy cosmic rays by detecting photons which accompany air showers developed in the earth's atmosphere. JEM-EUSO will be launched by Japanese H-II Transfer Vehicle(HTV) and mounted at the Exposed Facility of Japanese Experiment Module(JEM/EF) of ISS in the second phase of utilization plan. The telescope consists of high transmittance optical Fresnel lenses with a diameter of 2.5m, 200k channels of multianode- photomultiplier tubes, focal surface front-end, readout, trigger and system electronics. An infrared camera and a LIDAR system will be also used to monitor the earth's atmosphere.
