Acoustic Program for the PICASSO Dark Matter Detector.
Abstract
Since the mid 1930s there has been evidence that there is more gravitating material, in objects larger than the scale of a star, than can be accounted for by the amount of light coming from these objects. Today, observations indicate that about 85% of the gravitating material in the universe is of an unknown exotic nature. The PICASSO ( http://picasso.lps.umontreal.ca/ ) experiment is meant to be able to detect Weakly Interacting Massive Particles (WIMPS), which are promising particle candidates for the composition of this dark matter. The detector exploits the superheated droplet technique developed for neutron dosimetry. WIMP interactions with the droplets cause explosive liquid to gas phase transitions, which are detected acoustically. The research and development of the acoustics program for the project will be discussed.
