Searching method for energy spectrum with close peak positions suitable for neutron activation element analysis

Abstract

The invention discloses a searching method for energy spectrum with close peak positions suitable for neutron activation element analysis. The method comprises the following steps: numbering files in a spectrum-form knowledge base, constructing an index file which is a binary number of which the bit length is equal to the number of spectrum forms according to peak position information, carrying out corresponding Boolean calculation on the index file to obtain a spectrum form meeting a searching requirement in the spectrum-from knowledge base. According to the searching method, the spectrum form with a peak position close to the actually measured spectrum form can be quickly and accurately found out from the spectrum-form knowledge base, particularly when the quantity of the spectrum form files in the spectrum-form knowledge base is large enough and is much larger than a total address quantity of the spectrum form files. The advantages of the method are obviously embodied.

Description

technical field [0001] The invention relates to a data processing technical method for elemental analysis, in particular to a data processing technical method for neutron activation elemental analysis. Background technique [0002] Building materials, coal, thermal power, metallurgy, mining and other industries need to analyze the element composition and content of bulk materials on the conveyor belt to guide production. As a main online elemental analysis instrument, the multi-element analyzer using neutron activation prompt gamma analysis technology can realize continuous analysis of bulk materials on the conveyor belt. [0003] At present, the analysis principle of this type of instrument is that neutrons are irradiated on the material and react with the nuclei of each element in the material. Different elements emit characteristic γ-rays with different energies and intensities. By detecting the energy of characteristic γ-rays, the types of elements are identified. The e...
