Abstract

The invention discloses a hollow cylindrical collector diagnosing ionization chamber, and aims to solve the problems of small collection area and insufficient sensitivity of the ionization chamber in the prior art, further improve the performance of the ionization chamber, increase the measurement accuracy, increase the collection area, and lower the influence of combination loss on measurement. According to a technical scheme, the hollow cylindrical collector diagnosing ionization chamber comprises an ionization chamber shell, a collector, an insulator and an ionization chamber base, and is characterized in that the collector is arranged inside the ionization chamber shell; the lower part of the ionization chamber shell is provided with the ionization chamber base; the collector is arranged on the ionization chamber base through the insulator; an enclosed ionization chamber cavity is formed among the ionization chamber shell, the collector and the ionization chamber base; the collector is of a hollow structure; the collection area is increased through the hollow structure.

Description

technical field [0001] The invention relates to the technical field of ionizing radiation, in particular to a hollow cylindrical collector diagnostic ionization chamber. Background technique [0002] The ionization chamber is a kind of medium that uses air as the medium. By measuring the ionization charge formed by the interaction of the secondary electrons generated by X-rays and γ-rays on the wall of the ionization chamber and the indoor air, the radiation amount information is obtained, and then the radiation is measured by a secondary instrument. amount or radiation intensity. [0003] The ionization chamber is generally a cavity structure, and a certain DC voltage is applied to the shell and the collector to form an electric field, and the ionized charge is collected through the collector. The collector is generally a solid rod-shaped structure, and the whole or outer wall of the collector is conductive or coated with a conductive coating. Ionization chambers are gene...
