The concept of creating a real-time multi-detector neutron spectrometer is briefly outlined. It is shown that the main problem of its implementation is the lack of neutron detectors with diverse and precisely known spectral characteristics in the neutron energy range from 0.001 eV to 20 MeV. It is proposed to use scintillation polystyrene neutron detectors for these purposes, and four methods for forming various spectral characteristics of such detectors are described. A method for calculating spectral characteristics using a microscopic approach is substantiated. The results of calculating the spectral characteristics of such detectors using all four proposed methods for their formation are presented.
