Results And Status Of The PICASSO Experiment *

The PICASSO experiment searches for cold dark matter through the direct detection of weakly interacting massive particles (WIMPs) via their spin-dependent interactions with nuclei. It uses a superheated fluorocarbon, C₄F₁₀, as the active material. The first phase of the experiment (~20g of active mass) ended in January 2005. The PICASSO collaboration is presently working on the second phase with 32 4.5-liter detector modules. The total active mass of the experiment will be ~2.6 kg. In this talk, we are going to present the results of the first phase and give a status report on the second phase of the experiment.
