论文摘要
稻草管探测器是单线比例计数器，被广泛用作跟踪装置。我们已经用稻草管探测器原型进行了r $ \＆$ d。这项工作的动机是在高速率辐射下研究稻草管探测器的增益和能量分辨率的稳定性。合并了两种不同的方法来执行这项研究。研究了检测器的增益和能量分辨率以及其变化与环境温度和压力的变化。来自放射性源的X射线用于照射检测器，同一源也用于同时监测能量光谱以计算增益。本文讨论了在AR/CO $ _2 $ _2 $ _2 $ _2 $ _2 $ _2 $ imputture的增益和能量分辨率的变化。我们还估计了稻草管探测器的时间分辨率，这些探测器可以通过宇宙射线作为相同的气体混合物的触发来实现。本文介绍了测量过程和实验结果的细节。
Straw tube detectors are single wire proportional counters that are widely used as a tracking device. We have carried out R$\&$D with a straw tube detector prototype. The motivation of this work is to study the stability of the performance in terms of gain and energy resolution of the straw tube detectors under high rate radiation. Two different methods are incorporated to perform this study. The gain and energy resolution of the detector are studied along with its variation with ambient temperature and pressure. X-ray from a radioactive source is used to irradiate the detector and the same source is also used to monitor the energy spectra simultaneously for calculation of gain. Variation of the gain and energy resolution of the straw tube detector under X-ray irradiation in Ar/CO$_2$ gas mixture is discussed in this article. We have also estimated the time resolution of the straw tube detectors that can be best achieved with cosmic rays as trigger for the same gas mixture. The details of the measurement process and the experimental results are presented in this article.
