    Abstract The DArk Matter In CCDs at Modane (DAMIC-M) experiment is designed to search for light dark matter (mχ< 10 GeV/c2) 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.

    The DAMIC experiment employs large-area, thick charge-coupled devices (CCDs) to search for the interactions of low-mass dark matter particles in the galactic halo with silicon atoms in the CCD target. From 2017 to 2019, DAMIC collected data with a seven-CCD array (40-gram target) installed in the SNOLAB underground laboratory. We report dark-matter search results, including a conspicuous excess of events above the background model below 200 V_{ee} V e e , whose origin remains unknown. We present details of the published spectral analysis, and update on the deployment of skipper CCDs to perform a more precise measurement by early 2023.

    We report on recent progress in the search for dark matter particleswith masses from 1 Mev c ^{-2} − 2 to 1 Gev c ^{-2} − 2 .Several dark matter candidates in this mass range are expected togenerate measurable electronic-recoil signals in direct-detectionexperiments. We focus on dark matter particles scattering with electronsin semiconductor detectors since they have fundamentally the highestsensitivity due to their low ionization threshold. Charge-coupled device(CCD) silicon detectors are the leading technology, with significantprogress expected in the coming years. We present the status of the CCDprogram and briefly report on other efforts.
