Space charge in liquid argon time-projection chambers: a review of analytical and numerical models, and mitigation methods

Sandro Palestini, Filippo Resnati

摘要:

本文评述了电离探测器中的空间电荷问题,特别注意了液氩时间投影室的情况。沿漂移和横向重建坐标的影响的解析和数值描述。被认为是有限的电子寿命的情况下,双相离子反馈探测器,和探测器的漂移长度和宽度之间的小和可比的比率。两个设计解决方案,减轻影响进行了讨论。

英文摘要:

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.
