Description

The PICO collaboration has made significant progress in our understanding of the anomalous background events observed in bubble chamber dark matter searches. It is now understood that the background events are intrinsic to the technology, arising from the use of a normal fluid buffer layer to stabilize the surface of the superheated liquid in the bubble chamber. A new, simplified bubble chamber design has been developed that eliminates the use of a buffer liquid and is expected to eliminate the anomalous background events entirely. Plans, status, and projected dark matter sensitivity will be presented for a 40 liter demonstration device currently under construction and for the proposed PICO-500 bubble chamber.
