RUSCOSMIC — the new software toolbox for detailed analysis of cosmic ray interactions with matter

Abstract

At present, cosmic ray (CR) physics uses a considerable variety of methods for studying CR characteristics, and both primary and secondary fluxes, respectively. Experimental methods make the main contribution, using various types of detectors, but numerical methods increasingly complement it due to the active development in computer technology. This approach provides researchers with the most extensive information about details of the process or phenomenon and allows us to make the most competent conclusions. This paper presents a concept of the RUSCOSMIC software package based on the GEANT4 toolkit and representing a range of different numerical models for studying the CR passage through a matter of different systems. The obtained results represent response functions of the main radiation detectors as well as some typical characteristics of secondary CR fluxes. Comparative results also show the operation of the module verifica-tion of calculations with experimental data.

Updated Neutron‐Monitor Yield Function: Bridging Between In Situ and Ground‐Based Cosmic Ray Measurements

“…Here we used the NM registration efficiency according to Clem and Dorman (2000) and Maurchev and Balabin (2016), considering secondary neutrons, protons, positive and negative pions, and muons that contribute to the counts of the device Mishev et al, 2013). The computations were carried out separately for primary protons and particles with isotropic incidence in a wide energy range from about 0.5 GeV/nuc to 1 TeV/nuc.…”
