摘要
为了解大面积流气式多丝正比计数管工作空间的电场分布,本文提出了近似计算的物理模型,并在设定的条件下进行了数值计算,得到了电场分布的近似结果及其某些参数,诸如丝距和电极间距等的关系,以便于多丝正比计数管的正确设计和使用。
To understand the general distribution of the electric field intensity in the large-area flow-gas multiwire proportional counter, an approximate physical model is suggested for numerical calculation and the field intensity distribution that is the relative result based on limited conditions is obtained. The relation between the distribution and some geometric parameters of the counter, such as the interval between the neighbor wires and the anode-to-cathode distance, is presented. This is advantageous for the design and application of the multiwire proportional counter.
