摘要:

吸管探测器是广泛用作跟踪装置的单线正比计数器。我们已经进行了R $\&$ D与吸管探测器的原型。本工作的动机是研究在高速率辐射下的吸管探测器的增益和能量分辨率方面的性能的稳定性。采用两种不同的方法进行这项研究。研究了探测器的增益和能量分辨率随环境温度和压力的变化。来自放射源的X射线用于照射探测器,并且同一源还用于同时监测能谱以计算增益。本文讨论了在Ar/CO $_2$混合气体中X射线辐照下,吸管探测器的增益和能量分辨率的变化。我们还估计了吸管探测器的时间分辨率,可以最好地实现与宇宙射线作为触发相同的气体混合物。本文详细介绍了测量过程和实验结果。

英文摘要:

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.
