The PAMELA experiment is being conducted on board the RESURS DK1 satellite, launched into a near-Earth, near-polar orbit with an altitude of 350-610 km and an inclination of 70° on June 15, 2006. The apparatus comprises a magnetic spectrometer, an electromagnetic calorimeter (16X 0), a time-of-flight system, a neutron detector, an anticoincidence system, and a shower tail scintillator. It allows measurements of electron and positron fluxes in cosmic rays over a wide energy range of ∼100 MeV to several hundreds of GeVs. In this work, we present data on the electron and positron energy spectra in primary cosmic rays, obtained between June 2006 and December 2008.
