Abstract: The energy response ratio of the integrated multi-sphere neutron spectrometer when the seven measurement channels work simultaneously and each measurement channel works separately is calculated. The results of the energy response ratio of the two measuring modes are displayed the influence of the sphere-sphere interference decreases with the increase of the size of the slowing sphere, and the interference of the small-size slowing sphere increases with the increase of the neutron energy.

Key words: Integrated multi-sphere neutron spectrometer, sphere-sphere interference, energy response
