The NUCLEON experiment is being prepared for cosmic ray research at energy range 1012- 1015 eV. A new method has recently been proposed for measuring the spectra of primary CR particles by recording the spatial density of secondary charged particles produced by interactions of primary particles inside the setup. The photons are converted into charged electronpositron pairs by a tungsten converter. This method can be used to construct lightweight spectrometers of large geometrical factor for satellite experiments. The functional protoype of experimental device was tested by charge particles beams on SPS accelerator (CERN). The test results have demonstrated the feasibility of performing an orbital experiment with the proposed equipment.
