Special Issue Information

Dear Colleagues,

The exploration of space has always fascinated humanity, and particle physics has played an important role in exploring the mysteries of the universe. The study of energetic particles, such as cosmic rays, gammas and neutrinos, has provided valuable insights into the nature of our universe. On the other hand, the mechanisms of formation and accretion and the monitoring of particles trapped in the magnetic field at low energies are important as well. The detection particles in space and the modeling of their production mechanisms, their abundance, and their motion present unique challenges to the scientific community.

In both large-scale and small-scale space missions, particle detectors collect huge amounts of data that are used for observation and monitoring of the near Earth and cosmic environments. Moreover, the great statistical power coming from this data favors the application of new statistical methodologies and can be used to explore rare and complex phenomena and improve our understanding of the space environment.

This Special Issue will provide an opportunity for experts from various disciplines to share their ideas, concepts, and breakthroughs about new data analysis techniques and detector designs. The articles featured in this Special Issue may explore a wide array of topics, including, but not limited to, the following:

  • Data analysis techniques: this Special Issue will focus on advances in data analysis techniques for space physics experiments, with topics including sophisticated algorithms, statistical techniques, and machine learning techniques designed to extract valuable information from the large amount of data collected by detectors in space;
  • New detection methods: the contributions in this Special Issue will explore new methods of detection techniques in space physics;
  • Analysis of new phenomena: analysis of scarcely explored space physics phenomena.

Analyzing the isotopic composition of cosmic rays (CRs) provides valuable insights into the galactic environment and helps refine existing propagation models. A particular interest is devoted to secondary-to-primary ratios of light isotopic components of CRs, the measurement of which can provide complementary information with respect to secondary-to-primary ratios like B/C. Given the complexity of the concurrent measurement of velocity and momentum required to differentiate isotopes of the same Z, a task typically accomplished using magnetic spectrometers, existing measurements of these ratios only effectively characterize the low-energy region (below 1 GeV/nucl). This study introduces a novel technique for isotopic distinction in CRs at high energies up to 100 GeV/nucl based on multiple scattering, which, combined with the proposed measurement of velocity, represent an interesting alternative to magnetic spectrometers. The performance of this technique was assessed through a dedicated simulation using the GEANT4 package, with specific emphasis on Z = 1 isotopes. Full article

In high-altitude experiments to study the central cores of EAS at E0 ≳ 1016 eV (√s ≳ 5 TeV) using X-ray emulsion chambers and ionization calorimeters, phenomena such as the coplanarity of the arrival of the most energetic particles in super families of γ-rays and hadrons and a so-called Tien Shan effect (too slow absorption of cascades initiated by high-energy hadrons in the calorimeter) were observed. These effects could not be reproduced within the framework of theoretical models of the 80s and 90s. The coplanarity is explained via a process of coplanar generation of the most energetic secondary particles in interactions of super high-energy hadrons with nuclei of air atoms. Perhaps the Tien Shan effect could be explained using a high cross section for the generation of fragmentation-region charmed hadrons. To study these phenomena, a new set of detectors has been developed, including the world’s highest high-mountain ionization calorimeter, “Hadron-55”. This paper presents the initial experimental results. Full article
