- The JEM-EUSO Collaboration aims to study UltraHigh-Energy Cosmic Ray (UHECR) using a novel approach of looking down from space and using the atmosphere as a large detector to achieve a large effective area and therefore highstatistics on these events for the first time. For this purpose we have been developing a series of pathfinders operating from the ground, high altitude balloons and space, all sharing the same electronics, in particular the central data acquisition system. We report on the implementation and successful testing of the first-level trigger (L1) within the FPGA of the photo-detection module (PDM) board, which processes the signals from 36 64pixel MAPMTs with a time unit of 2.5 mu s to detect the passage of light from cosmic ray generated air-showers.

- Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, high-energy and ultrahigh-energy neutrinos probe fundamental physics from the TeV scale to the EeV scale and beyond. They are sensitive to physics both within and beyond the Standard Model through their production mechanisms and in their propagation over cosmological distances. They carry unique information about their extreme non-thermal sources by giving insight into regions that are opaque to electromagnetic radiation. This white paper describes the opportunities astrophysical neutrino observations offer for astrophysics and high-energy physics, today and in coming years.

The JEM-EUSO Program for UHECR Studies from Space

Konferensbidrag (refereegranskat)abstract
- To take up the challenge of understanding the origin of the ultra-high-energy cosmic rays (UHECRs), new observational means appear necessary. The JEM-EUSO Collaboration has undertaken to open the space road to UHECR studies. For more than a decade, it has been developing a realistic program to measure the UHECRs from space with unprecedented aperture, together with complementary scientific objectives in a broader multidisciplinary context. Several intermediate missions have already been completed (on the ground: EUSO-TA; under stratospheric ballons: EUSO-Balloon and EUSO-SPB1; in space: TUS, and on-board the ISS: MINI-EUSO), and others are in preparation for flight (EUSO-SPB2), under review (K-EUSO: currently on hold), or proposed for the next decade (POEMMA). We report on the general status of the JEM-EUSO program, underlining that its technology has now reached operational maturity, and is ready for actual cosmic-ray shower detection from above.

Neural Network Based Approach to Recognition of Meteor Tracks in the Mini-EUSO Telescope Data
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Mini-EUSO is a wide-angle fluorescence telescope that registers ultraviolet (UV) radiation in the nocturnal atmosphere of Earth from the International Space Station. Meteors are among multiple phenomena that manifest themselves not only in the visible range but also in the UV. We present two simple artificial neural networks that allow for recognizing meteor signals in the Mini-EUSO data with high accuracy in terms of a binary classification problem. We expect that similar architectures can be effectively used for signal recognition in other fluorescence telescopes, regardless of the nature of the signal. Due to their simplicity, the networks can be implemented in onboard electronics of future orbital or balloon experiments.
