TI - Measurements of the spatial-angular coordinates of the particle tracks in nuclear emulsion by means of the Fourier transform microscope
AB - The results of the measurements of the spatial-angular coordinates of large array, -500, of tracks in nuclear emulsion from protons with energy of 250 GeV by means of the Fourier-transform (FT) microscope of the direct observation are presented. The average linear density of silver grains in these particle tracks was equal to 37.6{+-}2.5 per 100 {mu}m. The angular divergence of protons in the primary beam was {approx}1 deg. The correspondence between the FT-pictures of proton tracks detected by means of the photodetectors and by means of the TV-system with CCD-matrix was proved unambiguously. The spatial resolution of the system ({approx}20 {mu}m) and its angular resolution ({approx}1.0`) were estimated. It is shown that in the optimal experimental conditions with illuminated region of the width 18 {mu}m instead of 40 {mu}m used in present experiments the system will enable one to detect and to measure the particle tracks with linear density of silver grains as small as 25 per 100 {mu}m. 5 refs.; 12 figs.
