Ground Level Enhancement (GLE) is a significant increase of the count rate registered on ground-based neutron monitors (NMs). So far, 72 GLEs have been recorded by the worldwide neutron monitor network since the 1950s. The energy spectrum of solar energetic particles (SEP) for these events varied quite a lot between the events, as measured directly and indirectly. Here we studied a statistical...

Magnetic spectrometer PAMELA was launched onboard a satellite Resurs-DK1
into low-Earth polar orbit with altitude 350-600 km to the study cosmic ray antiparticle fluxes in a wide energy range from ~ 100 MeV to hundreds GeV. This paper presents the results of observations of temporal variations of the positron and electron fluxes in the 2006-2015. The ratio of the positron and electron...

International space experiment PAMELA was started in 2006 and finished its work in 2016. The main aims of the experiment were the study of the spectra of cosmic rays and of their elemental composition, including the spectra of antiprotons and positrons in a wide energy range.
The objective of this work is to develop a methodology for the selection of electrons (including positrons) with...

Experimental measurements of the antiproton flux in the near Earth space are important for astrophysics, including the exploration of the hypothetical "dark" matter particle properties. From June 2006 up to January 2016, the scientific experiment PAMELA on board the spacecraft Resurs-DK1 was carrying out the study the various cosmic rays components in the wide energy range. PAMELA spectrometer...

One of main tasks in PAMELA experiment is identification of cosmic ray (CR) antiprotons on different
kinds of background. One example of such background at low energies are pi-meson particles which are
generated in elements of spectrometer construction by high-energy CR protons. We propose an approach
based on machine learning methods, in particular, Support Vector Machines (SVM). We use...

The sampling imaging electromagnetic calorimeter of $\approx 16.3$ radiation lengths and $\approx 0.6$ nuclear interaction length designed and constructed by the PAMELA collaboration as a part of the large magnetic spectrometer PAMELA. Calorimeter consists of 44 single-sided silicon sensor planes interleaved with 22 plates of tungsten absorber (thickness of each tungsten layer 0.26 cm)....

The PAMELA and the ARINA experiments are carried out on the board of satellite RESURS-DK1 since 2006. The main goal of the PAMELA instrument is measurements of high energy antiparticles in cosmic rays while the ARINA instrument is intended studying high energy charged particle bursts in the magnetosphere. Both of these experiments have a possibility to study trapped particles in the inner...

The fast multilayer scintillation detector of the new telescope-spectrometer for the ALFA-ELECTRON space experiment is in ground testing mode now. A module data control system for spectrometer is discussed. An algorithm for data treatment is presented. The device will planned to install on the outer surface of the Russian Segment of the International Space Station in 2018.
