Abstract

Variations of secondary cosmic rays on the Earth’s surface depend on the solar activity. To study these variations, neutron monitors and muon detectors are used. Observations of muons and hadrons complement each other in terms of the energies of the primary cosmic rays and their angular distribution. Muons save the direction of the motion of primary particles and make it possible to obtain the angular distribution of cosmic ray modulations using a single setup—as a muon hodoscope. This paper presents a comparison of variations of muon and neutron components of cosmic rays at the Earth surface at different phases of the solar activity in the period from 2008 to 2018. For the comparison, data of two neutron monitors (Moscow and Apatity stations) and the muon hodoscope URAGAN were used.
