It was the 15th of June of 2006 when the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome in Kazakstan. Then, for nearly ten years, PAMELA had been making high-precision measurements of the charged component of the cosmic radiation opening a new era of precision studies in cosmic rays and challenging our basic vision of the mechanisms of production, acceleration and...
Recently published spectra of comic ray protons measured by PAMELA instrument for the period 2006-2014 make it possible to perform a direct comparison with the neutron monitor (NM) count rates. Here we used the measured proton spectra as an input and computed, using two recent NM yield function models (Mishev et al., 2013 and Mangeard et al., 2016), the expected NM count rate. These computed...
The precision measurements of the monthly cosmic ray fluxes for the period
from May 2011 to May 2017 with the Alpha Magnetic Spectrometer on the
International Space Station are presented. This period covers the ascending
phase of solar cycle 24 together with the reversal of the Sun's magnetic
field polarity through the minimum. The detailed variations with time of
the fluxes are shown up...
