论文摘要
damic（CCDS中的暗物质）实验搜索了暗物质颗粒与核和电子中的电子相互作用的相互作用，这些颗粒的厚度厚度完全消耗的电荷耦合器件（CCD）。由于噪声低和黑暗电流低，因此DAMIC CCD对低质量暗物质颗粒预期的电离信号敏感（$ <10 $ GEV）。自2017年以来，已有40克目标检测器已在Snolab地下实验室收集了数据。将概述搜索DM电子散射和隐藏量吸收的结果，并报告了Wimps-Nucleon搜索的状态。一个新的检测器-DAMIC-M（MODANE的DAMIC） - 质量为1 kg和改进的CCD读数正在设计，并将安装在法国Modane的地下实验室。 DAMIC-M和不久的将来计划的现状将被介绍。
The DAMIC (Dark Matter in CCDs) experiment searches for the interactions of dark matter particles with the nuclei and the electrons in the silicon bulk of thick fully depleted charge-coupled devices (CCDs). Because of the low noise and low dark current, DAMIC CCDs are sensitive to the ionization signals expected from low-mass dark matter particles ($< 10$ GeV). A 40-gram target detector has collected data at the SNOLAB underground laboratory since 2017. Recent results from the searches for DM-electron scattering and hidden-photon absorption will be summarized and the status of WIMPs-nucleon search reported. A new detector -- DAMIC-M (DAMIC at Modane) -- with a mass-size of 1 kg and improved CCD readout is under design and will be installed at the underground laboratory of Modane, in France. The current status of DAMIC-M and the near future plans will be presented.
