Constraints on low-mass dark matter from CDMS-II and the development of highly-multiplexed next-generation detectors

Data from the Cryogenic Dark Matter Search (CDMS-II) have been reanalyzed
to give increased sensitivity to Weakly Interacting Massive Particles
(WIMPs) with masses below 10 GeV/c^2. Constraints on light WIMPs from an
analysis of the CDMS-II spectrum with a 2 keV recoil-energy threshold as
well as a search for annual modulation in the observed low-energy event
rate will be presented. These results directly constrain low-mass WIMP
interpretations of the potential signals reported by the DAMA/LIBRA,
CoGeNT and CRESST experiments. Progress developing radio-frequency
multiplexed detectors for next-generation rare-event searches will
also be discussed, including the first demonstration of energy and
position-resolved phonon-mediated particle detection using microwave
kinetic inductance detectors (MKIDs).
