在时间投影室中对弱相互作用大质量粒子的方向测量能够为其存在提供确凿证据，并有助于确定它们的性质。本文展示了时间投影室中几种可用于对方向敏感的暗物质搜索实验的电荷放大概念。我们展示了对100 keV以上的核反冲的“头尾”效应的重建，并在暗物质探测以及扩展到大型探测器体积的背景下讨论了探测器的性能。（C）2008爱思唯尔有限公司。保留所有权利。
Direction measurement of weakly interacting massive particles in time-projection chambers can provide definite evidence of their existence and help to determine their properties. This article demonstrates several concepts for charge amplification in time-projection chambers that can be used in direction-sensitive dark matter search experiments. We demonstrate reconstruction of the "head-tail" effect for nuclear recoils above 100 keV, and discuss the detector performance in the context of dark matter detection and scaling to large detector volumes.
