The technology I've had the honor to work on the past few years provides a wealth of information about each event, more so than any other direct detection experiment, and we are still learning how to optimally use all this information. In particular, this thesis is hopefully a good reference for those interested in the annual modulation limits placed on the low-energy portion of the CDMS II exposure, the design of the detectors for Super CDMS Soudan, and an overview of the extremely informative data these detectors produce. Some topics on which I spent significant efforts are described here only in overview (in particular the details of the CDMS II analysis, which has been laid out many times before), and some topics which are not described elsewhere are given a somewhat deeper treatment. The general abilities and sensitivities of both experiments are laid out, placing a special emphasis on the detector technology, and how this technology has evolved from the first to the second experiment. This thesis describes two such experimental efforts: CDMS II (2007-2009) and Super CDMS Soudan (ongoing). Detecting these dark matter particles directly, through hypothesized weak-force-mediated recoils with nuclear targets here on earth, could shed light on what these particles are, how they relate to the standard model, and how the standard model fits within a more fundamental understanding. Advancing the Search for Dark Matter: from CDMS II to Super CDMSĪn overwhelming proportion of the universe (83% by mass) is composed of particles we know next to nothing about.
