AI总结:

本文介绍DAMIC-M暗物质实验的低本底腔室(LBC)原型机,该装置自2022年起在法国莫达讷地下实验室运行,用于表征skipper CCD、研究暗电流、测量材料放射性纯度并测试各子系统,为千克级轻暗物质探测奠定基础。

摘要:

DArk Matter In CCDs at Modane(DAMIC-M)实验旨在法国莫达讷地下实验室(LSM)搜寻轻暗物质(m$_χ$<10 GeV/c$^2$)。DAMIC-M将使用skipper电荷耦合器件(CCDs)作为千克级有源探测器靶体。其单电子分辨率将实现电子伏特量级的能量阈值,从而对一系列隐藏扇区暗物质候选粒子达到世界领先的灵敏度。DAMIC-M原型机——低本底腔室(LBC)自2022年起在LSM采集数据。LBC提供了低本底环境,已用于表征skipper CCDs、研究暗电流以及测量DAMIC-M计划所用材料的放射性纯度。它还允许测试各种子系统,如读出电子学、数据采集软件和慢控制系统。本文介绍了LBC的技术设计与性能。

英文摘要:

The DArk Matter In CCDs at Modane (DAMIC-M) experiment is designed to search for light dark matter (m$_χ$<10\,GeV/c$^2$) at the Laboratoire Souterrain de Modane (LSM) in France. DAMIC-M will use skipper charge-coupled devices (CCDs) as a kg-scale active detector target. Its single-electron resolution will enable eV-scale energy thresholds and thus world-leading sensitivity to a range of hidden sector dark matter candidates. A DAMIC-M prototype, the Low Background Chamber (LBC), has been taking data at LSM since 2022. The LBC provides a low-background environment, which has been used to characterize skipper CCDs, study dark current, and measure radiopurity of materials planned for DAMIC-M. It also allows testing of various subsystems like readout electronics, data acquisition software, and slow control. This paper describes the technical design and performance of the LBC.
