Leake计数器几何响应的研究

Study on geomelrical response of Leake counters

研究了不同吸收层结构的Leake计数器的角响应和径向微分响应,结果表明,这些响应与吸收层结构基本无关。并且径向微分响应可用公式ε(P)=(1-((P/r))~2)1/2拟合。

Leake counters are commonly used in neutron dose-equivalent rate measnrement. In this paper, the directionality and collimated beam response of Leake counters are described.The experimental esults show that there is no directional dependence for Leake counters, and that Leake counters with different absorbers have similar collimated beam response,which can be expressed by the formula
