Problems solved by technology

[0003] The disadvantage of the existing single-layer hydrogen-containing proportional counter is that when it is applied to a multi-sphere neutron spectrum measurement device, the number of proportional counters required is large, which increases the difficulty of miniaturization and portability of the measurement equipment
And a detector can only measure one energy region at a time

Abstract

The invention provides a double-layer hydrogen-containing proportional counter for neutron energy spectrum measurement. The double-layer hydrogen-containing proportional counter comprises a net-shaped hemispheroid shell and a hemispheroid shell arranged outside the net-shaped hemispheroid shell in a sleeving mode. A ceramic gasket is arranged at the top of the net-shaped hemispheroid shell, a first outer cover is arranged at the top of the hemispheroid shell, a spring is arranged in the first outer cover, a ceramic pressing block is arranged at the top of the spring, and the spring is sleeved with an auxiliary ceramic block. The double-layer hydrogen-containing proportional counter for neutron energy spectrum measurement has the advantages that the energy spectrum measurement range of one hydrogen-containing proportional counter reaches the energy spectrum measurement range of two hydrogen-containing proportional counters, so that the hydrogen-containing proportional counter achieves balance between efficiency and volume, and miniaturization of equipment is facilitated. The neutron energy spectrum measurement efficiency is high, the volume of the hydrogen-containing proportional counter is small, the electrical interface is standard and reasonable, and the volume of the hydrogen-containing proportional counter and the energy spectrum measurement efficiency are optimally combined.

Description

technical field [0001] The invention specifically relates to a double-layer hydrogen-containing proportional counter for neutron energy spectrum measurement. Background technique [0002] The neutron energy spectrum measurement device uses a proportional counter to measure the neutron energy spectrum of the neutron radiation field. When the measurement energy range is thermal energy-4MeV, it is necessary to divide the measurement energy range, so as to use multiple detectors corresponding to different energy spectra to measure the neutron energy spectrum. At present, the commonly used measurement method is the multi-sphere neutron spectrometer, and its core idea is to cover and measure the neutron energy spectrum in different energy ranges through a single-layer hydrogen-containing proportional counter. The single-layer hydrogen-containing proportional counter is a hydrogen-containing proportional counter with only one layer of cathode casing. [0003] The disadvantage of ...
