Abstract

The PICASSO experiment, located in the Creighton Mine in Sudbury, Ontario, Canada, has demonstrated the viability of the superheated droplet technique in direct dark matter detection. Experimental sensitivity is to spin dependent elastic collisions with 1 9F as the active mass. Limits of σp - 1.31pb and σn = 21.5pb on the WIMP-proton and WIMP-neutron cross-sections respectively, at a 90% C.L. for a WIMP mass of 29 GeV/c2 were determined in 2004 using a small scale setup with 20g of active mass. Details of the PICASSO experiment, along with the improvements incorporated into the upcoming PICASSO 32 phase will be outlined in these proceedings.
