JEM-EUSO observational technique and exposure

Abstract: In this paper we describe the observational principle and the expected performances of JEM-EUSO. Designed as the first mission to explore the ultra-high energy universe from space, JEM-EUSO monitors the Earth's atmosphere at night to record the UV (300-430 nm) tracks generated by the Extensive Air Showers. We present the expected geometrical aperture and annual exposure in nadir and tilt modes for Ultra-High Energy Cosmic Rays as a function of the ISS altitude.

“…The UHECR shower Cherenkov mark background for the UAS detection could be suppressed via identification of the fluorescence track component of the same UHECR showers. Indeed, a shower which produces a strong Cherenkov mark containing more than N thr photoelectrons would typically have much more photoelectrons constituting an image of the EAS track [84]. This is true also for the showers with particularly strong Cherenkov marks on optically thick clouds [76].…”

“…Curve D) shows the estimated annual exposure for tilting JEM-EUSO by adjusting the observation area and SNR relative to those for the nadir observation [22]. S obs approximately scales by ∝ 1/ cos 3 ξ where ξ is the angle of tilting JEM-EUSO from the nadir.…”
