Hadronic cross section measurements with the DAMPE space mission using 20GeV-10TeV cosmic-ray protons and $^4$He
Precise direct cosmic-ray (CR) measurements provide an important probe to
study the energetic particle sources in our Galaxy, and the interstellar
environment through which these particles propagate. Uncertainties on hadronic
models, ion-nucleon cross sections in particular, are currently the limiting
factor towards obtaining more accurate CR ion flux measurements with
calorimetric space-based experiments. We present an energy-dependent
measurement of the inelastic cross section of protons and helium-4 nuclei
(alpha particles) on a Bi$_4$Ge$_3$O$_{12}$ target, using 88 months of data
collected by the DAMPE space mission. The kinetic energy range per nucleon of
the measurement points ranges from 18 GeV to 9 TeV for protons, and from 5
GeV/n to 3 TeV/n for helium-4 nuclei. Our results lead to a significant
improvement of the CR flux normalisation. In the case of helium-4, these
results correspond to the first cross section measurements on a heavy target
material at energies above 10 GeV/n.
