Description
The Extreme Universe Space Observatory (EUSO) to be accommodated in the
Japanese Experiment Module (JEM) of the International Space Station (ISS), JEM-EUSO,
is designed to discover the origin of ultrahigh energy cosmic rays by
observing extremely energetic extensive airshowers from space. The JEM-EUSO
design is based on a wide field of view (60$^o$) refractor with an ultrafast 0.3 M pixel
UV camera that records the extensive airshower fluorescence and backscattered
cherenkov. The main science goal of JEM-EUSO is to accumulate significantly higher
number of events than available from ground-based observatories at the highest
energies. The ISS orbit guarantees full sky coverage and its altitude provides the
ability to monitor two orders of magnitude more atmosphere when compared to
fluorescence telescopes on the ground. The large number of observed extremely
energetic events will provide a sky map of the relatively nearby sources. The
increase in statistics will also provide a measurement of the spectral shape around
the GZK feature, which may have a recovery depending on the maximum energy of
UHECR sources. Extremely energetic neutrinos may also be observed as well as fast
atmospheric phenomena in the UV. JEM-EUSO will also test physics beyond the
standard model by searching for the decay products of super-heavy dark matter and
tracks produced by strangelets or meteoroids.
