Properties of the difference method for searching for anisotropy of primary cosmic rays

Abstract

Methodical properties and features of the original difference method for searching for the anisotropy in the knee region of the primary cosmic ray energy spectrum are analyzed. It is shown that the method in which properties of particle fluxes, rather than intensities, are studied is stable to randomexperimental errors andmakes it possible to separate anomalies associatedwith the laboratory coordinate system from anomalies in the celestial coordinates. The method uses multiple scattering of charged particles in galactic magnetic fields for studying the entire celestial sphere, including sky regions beyond the installation line of sight.
