CCD detectors are pixelated silicon sensors. Charge collected in a pixel is shifted horizontally and vertically, and converted into a voltage measurement. The CCDs used in our research have extremely low noise, allowing them to measure very small signals.
Instead of using CCDs to collect light as astronomers do, we use them as particle detectors.
As particles pass through the CCD, some interact in a single place, and others leave tracks.
Experiments with CCDs
We use CCDs to search for dark matter in the DAMIC experiment.
