Abstract
With a prototype of a large hadron calorimeter, vertical cosmic-ray hadrons were recorded and the all-hadron flux was measured in the range from 10 GeV to 10 TeV. By means of a layer of scintillation counters, the neutral and charged components were identified and the ratio of neutral to charged hadrons could be extracted. From this ratio the charged-pion content is inferred using reasonable assumptions on the neutron-to-proton ratio. At the lower-energy end the data are compared firstly with existing results and secondly with theoretical calculations and Monte Carlo simulations.Keywords
