Descripción
The DAMIC-M (DArk MAtter in CCDs at a Modane) collaboration aims to directly detect dark matter in Charge-Coupled-Devices (CCDs). Utilizing fully depleted CCDs and a floating-gate (“skipper”) amplifier, the detector — operated deep underground at the Laboratoire Souterrain de Modane (LSM) — can resolve eV-scale interactions of Hidden Sector Dark Matter. The Low Background Chamber (LBC), the DAMIC-M prototype detector, features two Skipper-CCD modules with a combined mass of 25g. The LBC has set world leading limits on dark matter-electron scattering, excluding regions of parameter space corresponding to the freeze-in and freeze-out production mechanisms. We report on the science results from the LBC, the performance of the CCD Modules, and status of detector construction at LSM.
