“…Overall we can say, that for higher inclination angles, the track is shorter and so the light is seen by less pixel in less time, but the photon count grows in one pixel. The signal response of Mini-EUSO was simulated with the EUSO-OffLine framework adopted from Auger-OffLine [21,22]. The implementation was tested and is in agreement with laboratory measurements of the instrument.…”

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.

“…Originally developed for the ESA-EUSO mission, all the planned missions of the JEM-EUSO program have been implemented in ESAF in order to assess the full range of expected performance for cosmic ray observation. In parallel, efforts are currently being pursued to implement the Mini-EUSO configuration in the Offline code [8] which is the other official software framework of the JEM-EUSO collaboration.…”

The Mini-EUSO instrument is an UV telescope to be placed aboard the International Space Station (ISS) in the framework of the JEM-EUSO project. Mini-EUSO will map the Earth in the UV range (300-400 nm) with a spatial resolution of 5 km and a temporal resolution of 2.5 µs. Therefore, Mini-EUSO offers an excellent opportunity to study a variety of physics phenomena such as transient luminous events and meteors, as well as searching for strange quark matter and test the detection of space debris. Mini-EUSO will serve also as a pathfinder for the study of Extreme Energy Cosmic Rays from space. A review on the expected performance of Mini-EUSO in detecting a variety of physical phenomena simulated with the EUSO Simulation and Analysis Framework (ESAF) package is described. * Speaker. † This work is dedicated to the memory of Yoshiya Kawasaki and Jacek Karczmarczyk, members of the JEM-EUSO Collaboration, passed away in 2016.

“…The EUSO Simulation and Analysis Framework (ESAF) described in [9] and the Off line framework described in these proceedings [10] are the two software packages used for the showers simulation and reconstruction in the JEM-EUSO project and its pathfinders. The two frameworks have been developed independently and analysis results can be cross checked.…”

EUSO-TA is a ground-based cosmic ray fluorescence detector, pathfinder of the JEM-EUSO experiment, installed in 2013 at the Telescope Array (TA) site, in front of a TA fluorescence detector station at the Black Rock Mesa site (TA-FD), and completed with the focal surface detector in 2015, when it started to be operational. The data acquisition works in coincidence with TA-FD. This guarantees an easy identification of the cosmic ray events detected by EUSO-TA with reliability of the TA-FD event detection and reconstruction methods. Up to now, a few cosmic ray events have been identified. Two simulation software are developed for the JEM-EUSO detectors: ESAF and Off line . ESAF is the software package that has been developed in the efforts of the EUSO and JEM-EUSO projects; Off line was originally developed and successfully tested for years by the Auger Collaboration, and it has recently been adapted for the JEM-EUSO detectors. Thanks to the first events detected by EUSO-TA, ESAF and Off line have been improved in order to have a good comparison between data and simulations. This made the evaluation of the EUSO-TA detection threshold possible, with an Off line study based on the simulated air showers according to TA reconstruction. In parallel, an independent simulation to estimate the number of detectable events by EUSO-TA has been conducted using ESAF code. The simulation methods are described in this work, as well as the comparison between the number of actual detected events and the number of expected ones.
