“…In order to have a precise ratio of the photon rate per pixel from diffuse sources between JEM-EUSO and Mini-EUSO, a full simulation of JEM-EUSO and Mini-EUSO detectors was performed with ESAF simulation software [15]. In case of Mini-EUSO the overall efficiency of the detector was fine-tuned with ESAF, mainly acting at the level of MAPMT response, to match the measured one 𝜖 𝑀 𝐸 = 0.080 ± 0.015 (see the end-to-end in-flight calibration of Mini-EUSO reported in [19]) for a point-like source on ground.…”

Mini-EUSO is the first mission of the JEM-EUSO program on board the International Space Station. It was launched in August 2019 and it is operating since October 2019 being located in the Russian section (Zvezda module) of the station and viewing our planet from a nadir-facing UV-transparent window. The instrument is based on the concept of the original JEM-EUSO mission and consists of an optical system employing two Fresnel lenses of 25 cm each and a focal surface composed of 36 Multi-Anode Photomultiplier tubes, 64 channels each, for a total of 2304 channels with single photon counting sensitivity and an overall field of view of 44×44 • . Mini-EUSO can map the night-time Earth in the near UV range (predominantly between 290 nm and 430 nm), with a spatial resolution of about 6.3 km and different temporal resolutions of 2.5 𝜇s, 320 𝜇s and 41 ms. Mini-EUSO observations are extremely important to better assess the potential of a space-based detector in studying Ultra-High Energy Cosmic Rays (UHECRs) such as K-EUSO and POEMMA. In this contribution we focus the attention on the results of the UV measurements and we place them in the context of UHECR observations from space, namely the estimation of exposure.

“…To calculate the detector response, it is necessary to implement it within the simulator of the entire space experiment. Such models have been developed by the JEM-EUSO collaboration in the framework of the ESAF package (EUSO Simulation and Analysis Framework [50,51]). As a part of the calculations in ESAF, the consistency of the optics and electronics of the K-EUSO was checked (i.e., the comparison of the image size with the pixel size), as well as the calculation of the focusing efficiency and the effective light collection area (throughput).…”

“…In this section, estimations of the scientific performance of K-EUSO are presented following [56]. The study is based on intensive simulations with the ESAF framework [51] and their consequent analysis. The studies presented here must be regarded as preliminary since the configuration of the detector is still in the course of definition.…”

K-EUSO (KLYPVE-EUSO) is a planned orbital mission aimed at studying ultra-high energy cosmic rays (UHECRs) by detecting fluorescence and Cherenkov light emitted by extensive air showers in the nocturnal atmosphere of Earth in the ultraviolet (UV) range. The observatory is being developed within the JEM-EUSO collaboration and is planned to be deployed on the International Space Station after 2025 and operated for at least two years. The telescope, consisting of ∼105 independent pixels, will allow a spatial resolution of ∼0.6 km on the ground, and, from a 400 km altitude, it will achieve a large and full sky exposure to sample the highest energy range of the UHECR spectrum. We provide a comprehensive review of the current status of the development of the K-EUSO experiment, paying special attention to its hardware parts and expected performance. We demonstrate how results of the K-EUSO mission can complement the achievements of the existing ground-based experiments and push forward the intriguing studies of ultra-high energy cosmic rays, as well as bring new knowledge about other phenomena manifesting themselves in the atmosphere in the UV range.

“…Its phenomenology and the possible interpretations are reported in detail in [36]. In order to perform a deeper analysis of such candidates, a dedicated algorithm to reconstruct the arrival direction in TUS events and a specific version of ESAF [37] are being developed. The data acquired in meteor mode are being analyzed to search for slow events such as nuclearites.…”

The origin and nature of Ultra-High Energy Cosmic Rays (UHECRs) remain unsolved in contemporary astroparticle physics. To give an answer to these questions is rather challenging because of the extremely low flux of a few per km 2 per century at extreme energies (i.e. E > 5×10 19 eV). The central objective of the JEM-EUSO program, Joint Experiment Missions for Extreme Universe Space Observatory, is the realisation of an ambitious space-based mission devoted to UHECR science. A super-wide-field telescope will look down from space onto the night sky to detect UV photons emitted from air showers generated by UHECRs in the atmosphere. The JEM-EUSO program includes several missions from ground (EUSO-TA), from stratospheric balloons (EUSO-Balloon, EUSO-SPB1, EUSO-SPB2), and from space (TUS, Mini-EUSO) employing fluorescence detectors to demonstrate the UHECR observation from space and prepare the large size missions K-EUSO and POEMMA. We review the scientifical objectives associated with the developing projects of the JEM-EUSO program and the technological achievements allowing them.
