TL;DR
The NUCLEON space experiment measures cosmic ray nuclei at high energies, providing preliminary data on elemental ratios that reveal astrophysical phenomena in cosmic ray propagation.
Contribution
This paper presents initial results from the NUCLEON experiment on cosmic ray elemental ratios, offering new insights into high-energy cosmic ray composition.
Findings
Preliminary measurements of B/C, N/O, and subFe/Fe ratios.
Indications of astrophysical phenomena affecting cosmic ray propagation.
Data collected at energies up to 10^15 eV.
Abstract
The NUCLEON space observatory is a direct cosmic ray spectrometer designed to study cosmic ray nuclei with at energies eV. It was launched as an additional payload onboard the Russian Resource-P No. 2 satellite. In this work B/C, N/O and subFe/Fe ratios are presented. The experiment has worked for half of its expected time, so the data have preliminary status, but they already give clear indications of several astrophysical phenomena, which are briefly discussed in this paper.
