Description
The satellite-borne PAMELA experiment has been continuously collecting data since 15th June
2006, when it was launched from the Baikonur cosmodrome to detect the charged component of
cosmic rays over a wide energy range and with unprecedented statistics. The apparatus design
is particularly suited for particle and antiparticle identification. The PAMELA experiment has
measured the time variation of electron and positron spectrum at Earth in great detail, extending
the measurement down to 70 MeV. The spectra have been evaluated during the A<0 solar minimum of
cycle 23 i.e. from July 2006 to December 2009, over six-months intervals. These spectra provide important information for the
study of CR propagation inside the heliosphere and the investigation of the charge-sign dependent
solar modulation.
