WIMPs taking selfies: the DAMIC experiment at SNOLAB
Colloquia KICP63:442016Science & Tech
The DAMIC, Dark MAtter In CCDs, experiment employs the bulk silicon of ~mm-thick charge-coupled devices, CCDs, to detect coherent elastic scattering of Weakly-Interacting Massive Particles, WIMPs - putative yet-to-be-discovered particles which may explain the dark matter in the universe. This novel technique features an unprecedentedly low energy threshold for the detection of nuclear recoils, providing optimal sensitivity for low mass WIMPs. In addition, the spatial resolution of the CCDs, unique amongst dark matter detectors, provides powerful methods to identify and mitigate environmental and cosmogenic backgrounds. I will show recent results from DAMIC R&D data which demonstrate the potential of the CCD technology for WIMP detectors and first images from DAMIC100, a 100 g detector with 18 CCDs under installation at SNOLAB.
