DarkSide is a direct detection dark matter program at LNGS that is based on two phase depleted argon time projection chambers. A combination of low background construction techniques and active background suppression will give the DarkSide detectors very low and extremely well understood rates of background events. A 10 kg prototype detector is currently being operated at LNGS, while DarkSide-50, the first physics detector in the DarkSide program, is currently being constructed.
