Registration of Antiprotons in the Earth’s Radiation Belt in the PAMELA Experiment

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The PAMELA magnetic spectrometer on board the Resurs-DK1 spacecraft measured the fluxes of charged particles and antiparticles in cosmic radiation from June 2006 to January 2016. Based on the results from measurements, secondary antiprotons were first detected in near-Earth space in 2011, and the energy spectra of the albedo and captured components were determined in the 60 to 750 MeV range of energies. This work presents the results from measuring the antiproton flux in the Earth’s radiation belt according to the data of the PAMELA experiment, obtained over the period of the experiment, using improved algorithms for data processing and event selection.
