论文摘要
本报告概述了非常规使用电荷耦合设备（CCD）来搜索暗物质（DM）。 CCD（DAMIC实验）中的暗物质采用了厚，完全消耗的CCD的散装硅作为来自银河系颗粒暗物质相互作用产生的电离信号的靶标。 DAMIC的合作已经进行了广泛的表征努力，以了解这些CCD对低能核后坐力及其独特功能的反应，包括使用高空间分辨率来拒绝和研究背景。 DAMIC的初步结果证明了检测器的性能，提供了背景污染的测量，并证明了DM搜索的潜力，只有约40克检测器质量。实验的下一阶段DAMIC-M（Modane的CCD中的暗物质）将由KG大小的检测器组成，实施有史以来最庞大的CCD。这些CCD将具有子电子噪声，并将部署在法国的Laboratoire Souterrain de Modane的低放射性环境中。
This report presents an overview of the unconventional use of charge-coupled devices (CCDs) to search for Dark Matter (DM). The DArk Matter In CCDs (DAMIC Experiment) employs the bulk silicon of thick, fully-depleted CCDs as a target for ionization signals produced by interactions of particle dark matter from the galactic halo. The DAMIC collaboration has engaged in an extensive campaign of characterization efforts to understand the response of these CCDs to low-energy nuclear recoils and their unique capabilities, including the use of high spatial resolution for both the rejection and study of backgrounds. The preliminary results of DAMIC prove the performance of the detector, provide measurements of the background contamination and demonstrate the potentiality for DM searches, with only ~40 grams of detector mass. The next phase of the experiment, DAMIC-M (DArk Matter in CCDs at Modane), will consist of a kg-sized detector, implementing the most massive CCDs ever built. These CCDs will feature sub-electron noise and will be deployed in a low-radioactivity environment at the Laboratoire Souterrain de Modane in France.
