Abstract

A prototype segmented ionization chamber and corresponding waveform analysis algorithm for the segmented conductor ionization chamber for advanced spectroscopy targeting emitters of

$\alpha $

radiation (SCI-CASTER) project at the Simon Fraser University Nuclear Science Laboratory is discussed in this work. Provided that a robust method of extracting data from the detector is implemented, segmented ionization chambers allow for the measurement of both the energy and position of ionizing particles utilizing a single relatively inexpensive detector system. The waveform analyzer written for the SCI-CASTER project operates directly on raw digitized charge drift signals and generates a set of seven piecewise functions that completely describe the input waveform. This reduces the storage and computation time needed to extract timings and amplitudes from the data, allowing for rapid and adaptive offline data analysis. The performance of the waveform analyzer is summarized for a set of experiment runs, and measurements of timing, energy, and a demonstration of the positional sensitivity of the prototype detector are given.

SCI-CASTER 项目电离室信号的直接波形分析

本研究讨论了西蒙弗雷泽大学核科学实验室的分段导体电离室原型和相应的波形分析算法，该电离室用于针对α射线发射体的高级光谱分析（SCI-CASTER）项目。分段式电离室可以利用一个相对廉价的探测器系统测量电离粒子的能量和位置，但前提是从探测器中提取数据的稳健方法必须得到实施。为 SCI-CASTER 项目编写的波形分析器可直接对原始数字化电荷漂移信号进行操作，并生成一组可完整描述输入波形的七个片断函数。这减少了从数据中提取时序和振幅所需的存储和计算时间，从而实现了快速、自适应的离线数据分析。本文总结了波形分析仪在一系列实验运行中的性能，并给出了时序、能量的测量结果以及原型探测器位置灵敏度的演示。

期刊介绍： The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years. The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
