Improved Fabrication Method Of PICASSO Detectors*, Patrick Doane, for the PICASSO collaboration , Université de Montréal — The PICASSO collaboration uses superheated droplet detectors for its dark matter direct detection project. These detectors consist in a freon emulsion dispersed in a polymerized gel matrix. In this talk I will introduce a new method of emulsion fabrication, which has been recently developed. This method reduces significantly the alpha ray efficiency of PICASSO detectors, thereby producing lower background units.
