The DAMIC-100 dark matter detection experiment with CCDs at SNOLAB

Abstract

The DAMIC (Dark Matter in CCDs) experiment uses the fully depleted silicon of CCDs (Charge Coupled Devices) as a target for galactic dark matter. The ionization energy threshold for detecting nuclear recoils of dark matter reaches down to 50 eV$_{ee}$, resulting in better sensitivity to dark matter with mass below 5 GeV than other direct dark matter detection experiments. Installation of the DAMIC-100 experiment at SNOLAB is ongoing and we present our expected sensitivity, which will extend the reach to low-mass dark matter cross sections within a year of operation.
