. NUCLEON Experiment . General information . Instrument . Participants . Goal of experiment . Experiment NUCLEON aimed to direct measurements of the elemental energy spectra of high-energy (10 12 -10 15 eV) cosmic rays (CR) during 5 years (2010-2014) abroad Russian regular satellite. The main goal of this project -- to clarify the Cosmic Rays origin. Now it is expected that CR are accelerated in most catastrophic processes in the Galaxy and may be in Universe
