Method and device for simulating multisphere neutron spectrometer by utilizing position sensitive proportional counter tube

Abstract

The invention belongs to a neutron measurement technology, and particularly relates to a method and a device for simulating a multisphere neutron spectrometer by utilizing a position sensitive proportional counter tube. The method comprises the following steps of: making a slowing body to be in a conical shape that two bottom surfaces are buckled together; inserting a counting tube of a one-dimensional position sensitive neutron detector into the slowing body along the axial direction; and sequentially dividing the counting tube of the position sensitive neutron detector into a plurality of regions from the center to an edge of the counting tube of the position sensitive neutron detector along the axial direction, wherein each region respectively corresponds to each sphere of the multisphere neutron spectrometer. By adopting the special structures of the counting tube of the one-dimensional position sensitive neutron detector and the single-slowing body and dividing the regions, the invention simulates the work mode of the multisphere spectrometer, thereby keeping the advantage of the slowing body such as convenient measurement, absorbing the characteristic of the multisphere spectrometer such as good energy response, and being widely applicable to the field of neutron radiation measurement.

AI Technical Summary

Benefits of technology

This patented technology uses an improved type of detecting device called a neutron detection cell (NDC). It has several technical features that make it easier for researchers to measure high levels of radiation accurately compared with traditional methods like X ray fluorescence or atomic absorption techniques. Additionally, this design allows multiple spheres within the NDC to work together effectively at once without compromising its performance due to external influences such as temperature changes or other factors affecting their ability to function properly. Overall, these improvements improve the accuracy and efficiency of measuring nuclear weapons' threat level by providing more accurate measurements than current technologies.

Problems solved by technology

This technical issue addressed in this patented text relates to improving the accuracy of neutrino detection systems due to their lacking location sensibility or responsiveness to rapid changes caused by high levels of radioactive materials (RNAs). Current methods involve either expensive instrumentation that requires frequent maintenance or require long periods of time before being able to provide accurate measurements.
