[en] Methodical improvement of measurements of neutron scattering processes with the help of correlation spectrometer is described. It has been discussed how to construct reasonably a multidetector data acquisition system in the frame of limited volume of the computer memory. It is shown that in the case of a simultaneous measurement of the neutron inelastic scattering by six detectors only a half of the computer memory is necessary. A new flexible n-dimensional system of data acquisition is suggested which is capable of carrying out any n-dimensional analysis, where n = 1, 2, 3... In this experiment hardware real-time data selection is suggested
