论文摘要
Oscura实验将使用非常大的新型硅电荷耦合器件（CCD）搜索低质量的暗物质颗粒，其阈值是两个电子，总暴露于30 kg-yr。 R＆D工作于20财年开始，目前正在进入设计阶段，目的是准备在2024年末开始建造。Oscura将对与电子相互作用的Sub-Gev暗物质粒子具有前所未有的敏感性，探测了对500 kev和Dark Matter of Electrons for Electrons for Masses for Masses for Masses for Masses for Masses for Masses for Masses for Masses for Masses for Masses for Masses for Masses for s vose的群体的散射。 Oscura R＆D的工作在实验的主要技术挑战上取得了重大进展，其中最重要的是吸引新的铸造厂来制造CCD传感器，开发冷读数解决方案并了解实验背景。
The Oscura experiment will lead the search for low-mass dark matter particles using a very large array of novel silicon Charge Coupled Devices (CCDs) with a threshold of two electrons and with a total exposure of 30 kg-yr. The R&D effort, which began in FY20, is currently entering the design phase with the goal of being ready to start construction in late 2024. Oscura will have unprecedented sensitivity to sub-GeV dark matter particles that interact with electrons, probing dark matter-electron scattering for masses down to 500 keV and dark matter being absorbed by electrons for masses down to 1 eV. The Oscura R&D effort has made some significant progress on the main technical challenges of the experiment, of which the most significant are engaging new foundries for the fabrication of the CCD sensors, developing a cold readout solution, and understanding the experimental backgrounds.
