Abstract

Abstract

To eliminate the influence of the random background spectra on the prompt spectra in the associated particle technique，the random background spectra induced by non-tagged neutrons and the prompt spectra induced by tagged neutrons were studied in experiment. Measurements of the random background spectra in different condition were analyzed. The methods of acquiring random spectra were proposed for the bulk and small sample of different substances. For small sample，the background spectra can be obtained without the sample by selecting the same time window as in measuring the prompt spectra with the sample. In the case of the tagged neutron range less than the volume of the sample, the background spectra can be obtained with the sample by selecting the time window during the random time.
