A neutron spectrometer with three energy channels and a particle reception angle of 15° has been developed and installed for joint use with standard detectors at the cosmic ray station in Apatity. This configuration of the device allows one to study the degree of anisotropy of the particle flux. The characteristics of the detector (response function and the angle of reception of particles), as well as the geometric dimensions, were obtained by numerical simulation using the GEANT4 software package. During the operation of the device a database of observations was collected and preliminary results were obtained.
