论文摘要
回顾了电离探测器中的空间电荷主题,特别注意液体氩时间投影室的情况。呈现了对沿漂移和横向重构坐标的影响的分析和数值描述。考虑到有限的电子寿命,具有离子反馈的双相检测器的病例,以及在漂移长度和宽度之间较小且相当比率的检测器的病例。讨论了两种减轻效果的设计解决方案。
The subject of space charge in ionisation detectors is reviewed, with particular attention to the case of liquid argon time projection chambers. Analytical and numerical description of the effects on the reconstructed coordinates along the drift and the transverse directions are presented. The cases of limited electron lifetime, of dual-phase detectors with ion feedback, and of detectors with small and comparable ratio between drift length and width are considered. Two design solutions that mitigates the effects are discussed.
