We use the CORSIKA package (Heck et al., 1998) and AMS-01 flight data (Alcaraz et al., 2000) to evaluate the distribution of secondary particles in the Earth atmosphere. Distribution covers all ...longitudes and latitudes of STS-91 Space Shuttle flight trajectory to Mir Space Station. Moreover distribution covers all depth in the atmosphere in the evaluated area. We show distributions for e−, e+, μ+, μ−, gammas, hadrons and Cherenkov light from primary protons and helium component of cosmic rays flux. Our results compare favorably with other estimates made by different techniques.
We also estimate an UV light production (300–400nm) by electron component of secondaries at the top of the atmosphere and at ISS orbit.
The Mini-EUSO telescope is designed by the JEM-EUSO Collaboration to observe the UV emission of the Earth from the vantage point of the International Space Station (ISS) in low Earth orbit. The main ...goal of the mission is to map the Earth in the UV, thus increasing the technological readiness level of future EUSO experiments and to lay the groundwork for the detection of Extreme Energy Cosmic Rays (EECRs) from space (Ebisuzaki et al., 2014). Due to its high time resolution of 2.5 μs, Mini-EUSO is capable of detecting a wide range of UV phenomena in the Earth’s atmosphere. In order to maximise the scientific return of the mission, it is necessary to implement a multi-level trigger logic for data selection over different timescales. This logic is key to the success of the mission and thus must be thoroughly tested and carefully integrated into the data processing system prior to the launch. This article introduces the motivation behind the trigger design and details the integration and testing of the logic.

EUSO-SPB (Extreme Universe Space Observatory-Super Pressure Balloon) was the first mission of the JEM-EUSO program which implemented the First Level Trigger (FLT) logic to detect Ultra-High Energy ...Cosmic Rays (UHECRs) following the scheme developed for the JEM-EUSO mission. Experimental results matched the expected behavior of the logic and satisfied the requirements conceived for the FLT. The sensitivity of EUSO-SPB to the detection of UHECRs was established.
•The performance of First Level Trigger of JEM-EUSO embedded in hardware and tested with EUSO-SPB confirms expected behavior of the designed logic.•The energy threshold of EUSO-SPB confirms simulations.•A first estimation of the number of Ultra-High Energy Cosmic Rays that should have been detected by EUSO-SPB in flight is presented.
