论文摘要
DAMIC-M(CCDS中的暗物质)实验采用厚,完全消耗的硅充电耦合器件(CCD)来搜索目标暴露1 kg年的暗物质颗粒。 CCD中实现的新型船长读数通过对单个像素电荷的多个非破坏性测量结果提供单电子分辨率,从而将检测阈值推向EV量表。 DAMIC-M将通过几个数量级的探索来促进暗物质粒子假说,特别是与所谓的“隐藏部门”有关的候选人。最近在Laboratoire Souterrain de Modane上安装了一个原型,低背景室(LBC),具有20克背景船长CCD,目前已在Laboratoire Souterrain de Modane上安装。我们将报告DAMIC-M实验的状态,并通过LBC调试数据获得了首先获得的结果。
The DAMIC-M (DArk Matter In CCDs at Modane) experiment employs thick, fully depleted silicon charged-coupled devices (CCDs) to search for dark matter particles with a target exposure of 1 kg-year. A novel skipper readout implemented in the CCDs provides single electron resolution through multiple non-destructive measurements of the individual pixel charge, pushing the detection threshold to the eV-scale. DAMIC-M will advance by several orders of magnitude the exploration of the dark matter particle hypothesis, in particular of candidates pertaining to the so-called "hidden sector." A prototype, the Low Background Chamber (LBC), with 20g of low background Skipper CCDs, has been recently installed at Laboratoire Souterrain de Modane and is currently taking data. We will report the status of the DAMIC-M experiment and first results obtained with LBC commissioning data.
