Light component of cosmic rays' estimation in the range 200–10000 TeV by hybrid method

We presented new results on measuring the spectrum of the light component (protons + helium) of cosmic rays in the classical knee region in the primary cosmic rays' spectrum at an energy of , obtained from hybrid data of the TAIGA experiment. In hybrid method Cherenkov light created in atmosphere by extensive air showers is recorded simultaneously by two (IACT + HiSCORE) installations. At the same time, the separation of showers from the light component is carried out for the first time according to the image parameters recorded by the IACT atmospheric image telescope. The developed approach to the separation of the light component is based on and confirmed by Monte Carlo calculations. In the obtained spectrum of the light component in the energy range 200–20000 TeV, a pronounced feature is observed at an energy of about 3 PeV.
