                 Searching for Dark Matter with Bubble Chambers

   Searches for dark matter particles are expected to dramatically improve in
sensitivity over the next decade. One of the new techniques is a revival of the
      bubble chamber, an instrument previously thought to be obsolete. The
  conventional bubble chambers responsible for discoveries in particle physics
  from the 1950*s-80`s would be unsuitable for detection of Weakly Interacting
      Massive dark matter Particles (WIMPs), due to instabilities and high
 backgrounds. However, these problems can be overcome with alternative designs.
Small prototype chambers have already achieved interesting sensitivity and much
         larger, enormously more sensitive ones should be coming soon.
