Measurement of the total spectrum of electrons and positrons in the energy range of 300 1500 GeV in the PAMELA experiment with the aid of a sampling calorimeter and a neutron detector
A method based on the use of a sampling calorimeter was developed for measuring the total energy spectrum of electrons and positrons from high energy cosmic rays in the PAMELA satellite borne experiment. This made it possible to extend the range of energies accessible to measurements by the magnetic system of the PAMELA spectrometer. Themethod involves a procedure for selecting electrons on the basis of features of a secondary particle shower in the calorimeter. The results obtained by measuring the total spectrum of cosmic ray electrons and positrons in the energy range of 300 1500 GeV by the method in question are presented on the basis of data accumulated over a period spanning 2006 and 2013.
