Abstract :
An experiment to study cosmic ray protons and nuclei in the 1011–1014 eV energy range is discussed. The instrument measures the number of particles in a shower, generated by the primary particle in a lead absorber (∼14 cm thick). The instrument consists of two Cherenkov charge detectors, and two plastic scintillators viewed by 4 photo multipliers under a lead absorber (see Fig.1). The geometry factor of the instrument with account for the probability of particle recording is 0.015 m2 sr. Computer simulations of the instrument operation were made to make sure that the instrument is capable of measuring irregularities in the proton spectrum, which presumably exist at E∼1012 eV.
