Description
Until now, several space experiments have observed a bump structure near 10 TV of rigidity in the primary cosmic ray spectrum. In this work, the energy spectrum measurement of sub-iron nuclei (Sc, Ti, V, Cr, Mn) with the DAMPE satellite is reported from 300 GeV up to 2 PeV , thus covering the energy range where a bump structure in the primary cosmic rays has been detected. By Providing the energy spectrum of sub-iron nuclei in this energy range and the ratio of sub-iron to iron is crucial for studying the origin of the bump structure, as well for investigating the propagation of heavy cosmic rays through the Galaxy. A possible enhancement of the charge resolution and the analysis of the fragmentation of heavy nuclei, will allow to provide a precise measurement of the energy spectra of this group of secondary cosmic rays.
