Description
The COUPP and PICASSO collaborations have recently combined efforts to develop superheated-liquid dark matter detectors under the new name PICO. The first joint effort is a refurbishing of the old COUPP-4 bubble chamber detector with 2 liters of perfluoropropane (C3F8) as a new target fluid. This project, known as PICOlite, will have excellent sensitivity to ~10GeV WIMPs by virtue of the light nuclear targets and the inherent superb gamma rejection for nuclear recoil thresholds as low as 3keV. PICOlite is projected to provide a definitive test this year of the recent dark matter hints in this mass range from CDMS-II, CoGent and other experiments.
