The Cosmic-Ray composition between 2 PeV and 2 EeV observed with the TALE detector in monocular mode

Popis výsledku v původním jazyce

We report on a measurement of the cosmic-ray composition by the Telescope Array Low-energy Extension (TALE) air fluorescence detector (FD). By making use of the Cherenkov light signal in addition to air fluorescence light from cosmic-ray (CR)-induced extensive air showers, the TALE FD can measure the properties of the cosmic rays with energies as low as ∼2 PeV and exceeding 1 EeV. In this paper, we present results on the measurement of distributions of showers observed over this energy range. Data collected over a period of ∼4 yr were analyzed for this study. The resulting distributions are compared to the Monte Carlo (MC) simulated data distributions for primary cosmic rays with varying composition and a four-component fit is performed. The comparison and fit are performed for energy bins, of width 0.1 or 0.2 in , spanning the full range of the measured energies. We also examine the mean value as a function of energy for cosmic rays with energies greater than 1015.8 eV.
