Description
JEM-EUSO is a space mission devoted to the investigation of Ultra-High Energy
Cosmic Rays and Neutrinos (E $> 5 \cdot 10^{19}$ eV) from the International
Space Station (ISS). The telescope is formed by a system of three Fresnel
lenses and a focal surface filled with multi anode photomultipliers read
by a front-end electronics based on the single photon counting.
The trigger system should face different major challenging points:
a) to manage a large number of pixels ($\sim 3 \cdot 10^5$);
b) to use a very fast, low power consuming, and radiation hard electronics;
c) to achieve a high signal-to-noise performance and flexibility;
d) to cope with the limited down-link transmission rate from the ISS to
Earth.
In this contribution the general overview of the first trigger
level for cosmic ray detection is reviewed; tests that validate its
performance are discussed.
