In this paper, we study the effect of decreasing aperture diameter on signal transmission from scintillator to PMT. The apertures have been inserted directly between and photomultiplier. Three different diameters used over a wide energy range. A newly developed fast digital spectrometer has utilized for experimental measurement in radial channel VR-1 research reactor. detector signals with without measured evaluated. aim our was determine spectral quality, range evaluated physical quantities.
