论文摘要
对低收益效应的研究不仅需要良好的原始数据质量，而且还需要对其处理程序提高选择有用事件的效率的高要求。大型圆柱体比例计数器的静电拓扑的利用允许改善有关多点事件主要电离的信息的外推。使用外部$^{109} $ CD-SORCE的长期校准测量允许开发一种新方法，用于分析较大比例计数器的脉冲形状。对电流电离的电子云中电流云的优化分析可改善分辨率和能量校准。结果，选择有用事件的效率提高了25 \％。
The study of low-yield effects requires not only good quality of the original data but also puts high requirements for their processing procedures to increase the efficiency of the selection of useful events. The exploiting of the large cylindrical proportional counter's electrostatic topology allows improving the extrapolation of information about the primary ionization of a multipoint event. Long-term calibration measurements with an external $^{109}$Cd-source allowed the development of a new method for analyzing the pulse shape from a sizeable proportional counter. Optimized analysis of the current's pulse shape from the electron cloud of primary ionization in the counter improved the resolution and energy calibration. As a result, the efficiency of selecting useful events was increased by 25\%.
