“…The Mini-EUSO configuration has been included in the EUSO Simulation and Analysis Software (ESAF) package [6]. ESAF is one of the official software tools to perform simulations of Extensive Air Shower (EAS) development, photon production and transport through the atmo- sphere and detector response for optics and electronics.…”

more than 35 sessions have been performed for a total of 52 hours of observations. The detector has been observing Earth at night-time in the UV range and detected a wide variety of transient sources all of which have been modeled through Monte Carlo simulations. Mini-EUSO is also capable of detecting meteors and potentially space debris and we performed simulations for such events to estimate their impact on future missions for cosmic ray science from space. We show here examples of the simulation work done in this framework to analyze the Mini-EUSO data. The expected response of Mini-EUSO with respect to ultra high energy cosmic ray showers has been studied. The efficiency curve of Mini-EUSO as a function of primary energy has been estimated and the energy threshold for Cosmic Rays has been placed to be above 10 21 eV. We compared the morphology of several transient events detected during the mission with cosmic ray simulations and excluded that they can be due to cosmic ray showers. To validate the energy threshold of the detector, a system of ground based flashers is being used for end-to-end calibration purposes. We therefore implemented a parameterization of such flashers into the JEM-EUSO simulation framework and studied the response of the detector with respect to such sources.

“…These could help improve the understanding of the formation mechanisms of filaments plasma structures, complementing atmospheric science experiments. The TLEs simulated in the ESAF is described here [6]. Mini-EUSO is also capable of detecting slower events such as meteors, fireballs, strange quark matter (SQM) and space debris with magnitudes of M < +5.…”

Mini-EUSO is a mission of the JEM-EUSO program flying onboard the International Space Station since August 2019. Since the first data acquisition in October 2019, more than 35 sessions have been performed for a total of 52 hours of observations. The detector has been observing Earth at night-time in the UV range and detected a wide variety of transient sources all of which have been modeled through Monte Carlo simulations. Mini-EUSO is also capable of detecting meteors and potentially space debris and we performed simulations for such events to estimate their impact on future missions for cosmic ray science from space.

“…Placed inside the International Space Station (ISS) at 400 km MSL behind a UV-transparent window in nadir direction [7]. Mini-EUSO has a multi-trigger design and thus, three different time resolutions, providing the opportunity to measure various UV light signals like Earth's UV emission, and emissions from atmospheric sources, meteroides or bioluminescence [8,9,10]. Furthermore, it is also capable of detecting space debris.…”

Mini-EUSO (Extreme Universe Space Observatory) is a small-scale prototype cosmic-ray detector that will measure Earth's UV emission and other atmospheric phenomena from space. It will be placed in the International Space Station (ISS) behind a UV-transparent window looking to the nadir. The launch is planned this year (2019). Consisting of a multi-anode photomultiplier (MAPMT) camera and a 25 cm diameter Fresnel lens system, Mini-EUSO has a 44 • field of view (FoV), a 6.5 km 2 spatial resolution on the ground and a 2.5 µs temporal resolution. In principle, Mini-EUSO will be sensitive to extensive air shower (EAS) from cosmic-rays with energies above 10 21 eV. A mobile, steerable UV laser system will be used to test the expected energy threshold and performance of Mini-EUSO. The laser system will be driven to remote locations in the Western US and aimed across the field of view of Mini-EUSO when the ISS passes overhead during dark nights. It will emit pulsed 355 nm UV laser light to produce a short speed-of-light track in the detector. The brightness of this track will be similar to the track from an EAS resulting from a cosmic-ray of up to 10 21 eV. The laser energy is selectable with a maximum of around 90 mJ per pulse. The energy calibration factor is stable within 5 %. The characteristics of the laser system and Mini-EUSO have been implemented inside the JEM-EUSO OffLine software framework, and laser simulation studies are ongoing to determine the best way to perform a field measurement.
