Radiation Hardness Assurance for the JEM-EUSO Space Mission

This analysis documents the process and results of reliability determination of the PhotoMultiplier Tube (PMT) components of the JEM-EUSO telescope under the different radiation sources, UV radiation, Total Ionizing Doses (TIDs), and Single Event Transients. In terms of UV Ionization, the transmittance of the glass of the PMTs during the 5-year duration of the mission is greater than 99.98%, th...

A New LIDAR Method using MEMS Micromirror Array for the JEM-EUSO mission

LIDAR (LIght Detection And Ranging) is an important method in measuring atmospheric transparency that is used to correct fluorescence light yield from extensive air showers. For the JEM-EUSO (Extreme Universe Space Observatory on Japanese Experimental Module) mission to observe ultra-high cosmic rays at the ISS (International Space Station) orbiting at 400 km altitude the method is used also to...

Sensitivity of JEM-EUSO to GRB Neutrinos

JEM-EUSO is a mission to study ultrahigh-energy cosmic rays (UHECRs) by measuring the fluorescence light from giant air showers at the altitude of the International Space Station. In the tilted mode, JEM-EUSO will become very sensitive to the Čerenkov light from the earth skimming tau neutrinos at the energy range of 10eV. In this paper we will discuss high-energy tau neutrinos from nearby gamm...

The potential of the JEM-EUSO telescope for the astrophysics of extreme energy photons

Extreme energy photons are expected to be a minor component of the ultra high energy cosmic rays. Nevertheless, they are the carriers of very important astrophysical information related to the origin and propagation of such ultra energetic particles. JEM-EUSO is an orbital fluorescence telescope intended to observe the highest energy component of the cosmic rays, including photons and neutrinos...
