Abstract:
'Dark Matter Particle Explorer（DAMPE) is a calorimetric-type, satellite-borne detector for observations of high energy electrons, gamma-rays, and cosmic-ray nuclei. Using five years data recorded with DAMPE from January 1, 2016 to December 31, 2020, we measure the spectrum of iron nuclei in a wide energy range. Detailed studies of the fragmentation of iron in the detector have been performed using Monte Carlo simulations. The DAMPE result shows good consistency with previous measurements by other experiments below hundreds of GeV/n, and improves the precision at higher energies.'
