SuperCDMS status from Soudan and plans for SNOLab

2013
Matter, as we know it, makes up less than 5% of the Universe. Various astrophysicalobservations have confirmed that one quarter of the Universe and most of the matter content in the Universe is made up of Dark Matter. The nature of Dark Matteris yet to be discovered and is one of the biggest questions in Physics. Particle Physicscombined with astrophysicalmeasurements of the abundance gives rise to a Dark Mattercandidate called Weakly Interacting Massive Particle( WIMP). The low density of WIMPsin the galaxies and the extremely weak nature of the interaction with ordinary matter make detection of the WIMPan extraordinarily challenging task, with abundant fakes from various radioactive and cosmogenic backgrounds with much stronger electromagnetic interaction. The extremely weak nature of the WIMPinteraction dictates detectors that have extremely low naturally occurring radioactive background, a large active volume (mass) of sensitive detector material to maximize statistics, a highly efficient detector based rejection mechanism for the dominant electromagnetic background and sophisticated analysis techniques to reject any residual background. This paper describes the status of the SuperCDMS experiment.
