稀有液体量热计和时间投影室中的空间电荷效应

Space Charge Effects in Noble Liquid Calorimeters and Time Projection Chambers

Sandro Palestini

摘要:

电离探测器中的空间电荷的主题进行了审查,显示如何观察和用于描述的效果的形式主义已经演变,开始应用到量热计,并达到最近的大尺寸时间投影室。一般标度律,和不同的方式来呈现和建模的影响。讨论了探测器侧面的空间电荷效应和边界条件之间的关系,以及减轻部分效应的设计方案。漂移长度和横向探测器尺寸的相对大小的影响进行了说明。简要讨论了校准方法。

英文摘要:

The subject of space charge in ionization detectors is reviewed, showing how the observations and the formalism used to describe the effects have evolved, starting with applications to calorimeters and reaching recent, large-size time projection chambers. General scaling laws, and different ways to present and model the effects are presented. The relation between space-charge effects and the boundary conditions imposed on the side faces of the detector are discussed, together with a design solution that mitigates part of the effects. The implications of the relative size of drift length and transverse detector size are illustrated. Calibration methods are briefly discussed.
