How dark matter can be detected in a CCD
The innermost layer is made of ancient lead recovered from a sunken Spanish galleon and a Roman ship.
With unprecedented resolution and energy threshold, DAMIC-M CCDs have been demonstrated to detect single electrons.
DAMIC-M will achieve the sensitivity to detect signatures of certain predictions of dark matter that have not before been detected.
The detector is surrounded by an onion of layers of different shielding materials to keep everyday radiation away from the CCDs.
Dark Matter in CCDs at Modane
DAMIC (Dark Matter in CCDs) is an experiment using CCD detectors to search for dark matter. Click on the figures above for more information.
DAMIC-M (DAMIC in Modane) is the newest phase of the experiment, which will be operated under 1700 meters of rock at Le Laboratoire Souterrain de Modane.
