© 2019 Author(s).We present the energy dependence of the cross section for the inelastic interaction of protons with the tungsten in the energy range from an order GeV to a hundred GeV using the data of the PAMELA space experiment. It was intended for the precision measurements of the cosmic ray fluxes of different nature and include a set of detectors for the reliable determination of the particle characteristics. We present the comparison of the obtained results with the measurements at accelerators and with existing theoretical models. The results of the work can be demanded for the development of numerical models describing particle's interactions.

We have used different types of harmonic analysis, such as Fourier and wavelet analysis. The time profiles and amplitude dependences for the rigidities of cosmic ray particles from ~300 MV to tens of GV were obtained. It is shown that the amplitude-rigidity dependence cannot be described by a power law at low energies, the amplitude decreases with decreasing rigidity starting from ~ 1 GV. For a physical interpretation, we have studied the relationship between the 27-day variations of GCR and heliospheric parameters: solar wind velocity and heliospheric magnetic field.

All rights reserved.Using measurements from the PAMELA and ARINA spectrometers on board the Resurs-DK1 satellite, we have examined the 27 day intensity variations in galactic cosmic ray (GCR) proton fluxes in 2007–2008. The PAMELA and ARINA data allow for the first time a study of time profiles and the rigidity dependence of the 27 day variations observed directly in space in a wide rigidity range from ∼300 MV to several gigavolts. We find that the rigidity dependence of the amplitude of the 27 day GCR variations cannot be described by the same power law at both low and high energies. A flat interval occurs at rigidity R = 〈0.6–1.0〉 GV with a power-law index γ = −0.13 ± 0.44 for PAMELA, whereas for R ≥ 1 GV, the power-law dependence is evident with index γ = −0.51 ± 0.11. We describe the rigidity dependence of the 27 day GCR variations for PAMELA and ARINA data in the framework of the modulation potential concept using the force-field approximation for GCR transport. For a physical interpretation, we have considered the relationship between the 27 day GCR variations and solar wind plasma and other heliospheric parameters. Moreover, we have discussed possible implications of MHD modeling of the solar wind plasma together with a stochastic GCR transport model concerning the effects of corotating interaction regions.
