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.
