Abstract

The temporal characteristics of a time-of-flight spectrometer installed on the first channel of the IBR-2 reactor are investigated. A change in the flash time of the reactor relative to the start depending on the measurement time from the beginning of the reactor operation cycle is discovered. The neutron deceleration time is measured as a function of the neutron wavelength. A dependence of the half-width of the reflections on the neutron wavelength is established. The measurements are carried out in a wide range of Bragg angles from 0.0567232 to 0.34180977 rad (from ~3° to ~19°). An estimate is made for the mosaic pattern of a single crystal.
