“…Here a very direct and model-independent argument is given in favor of expecting consistent results from both methods, that is, if all the data processing is performed correctly. The basic value which is used in the calorimetric method to reconstruct the spectra of the particles is the energy deposited in the detectors of the calorimeter Ed; and in the KLEM method, the main parameter is a specially constructed estimator S, which is related lg(Ed/MIP) 3 3.5 to the number of secondary particles with a high pseudorapidity after the first interaction (see Equation (3.1) below, for details see also [15][16][17][18][19]). Figure 5 shows a scatter plot of the Ed and S variables, measured for the same event.…”

The NUCLEON experiment was designed to study the chemical composition and energy spectra of galactic cosmic ray nuclei from protons to zinc at energies of ∼ 10 11 -10 15 eV per particle. The research was carried out with the NUCLEON scientific equipment installed on the Russian satellite "Resource-P" No. 2 as an additional payload. This article presents the results for the measured nuclei spectra related to the first approximately 250 days of the scientific data collection during 2015 and 2016. The all-particle spectrum and the spectra of p, He, C, O, Ne, Mg, Si and Fe are presented. Some interesting ratios of the spectra are also presented and discussed. The experiment is now in its beginning stage and the data still have a preliminary character, but they already give numerous indications of the existence of various non-canonical phenomena in the physics of cosmic rays, which are expressed in the violation of a simple universal power law of the energy spectra. These features of the data are briefly discussed.

“…The NUCLEON space experiment was designed mainly to measure the spectra of cosmic ray nuclei with an individual charge resolution in the energy range from a few TeV to 1 PeV per particle, while having a lower energy threshold of a few hundred GeV. The most important feature of the NUCLEON detector is the implementation of two different particle energy measurement methods: the first uses an ionization calorimeter, and the second is a kinematic method, the Kinematic Lightweight Energy Meter (KLEM) [3,4,5,6,7], which is based on the measurement of the multiplicity of secondary particles after the first nuclear interaction of a primary particle with a target of the spectrometer. The advantage of the KLEM method compared to the conventional calorimetric method is the ability to provide a high aperture of the device with a low weight of the equipment.…”

“…A new energy measurement method, KLEM (Kinematic Lightweight Energy Meter), was proposed in [17][18][19][20][21]. The technique can be used over a wide range of energies (10 11 -10 16 eV) and gives an energy resolution of 70% or better, according to simulation results.…”
