The JEM-EUSO Mission
Abstract
The JEM-EUSO experiment, Extreme Universe Space Observatory on the Japanese Module of the International Space Station, aims at unveiling the nature and the origin of the ultra high energy cosmic rays (UHECRs), and to address basic problems of fundamental physics at extreme energies. The instrument is designed to measure the arrival direction, the energy and, possibly, the nature of these particles. It basically consists of a wide-field of view telescope that looks down from the International Space Station during night-time to detect UV photons emitted from air showers generated by UHECRs in the atmosphere, in order to identify their individual sources and their association with known nearby astronomical objects. An infrared camera and an atmosphere monitoring system improve the performance of the instrument. Key parts have been developed and will be used in the EUSO-TA, EUSO-Balloon and Mini-EUSO pathfinders. 15 Countries, 76 Institutes and about 300 researchers are collaborating in JEM-EUSO.
