Description
The Cryogenic Dark Matter Search (CDMS) experiment employs germanium and silicon
semiconductor crystals to perform direct searches of Dark Matter in the form of
Weakly Interacting Massive Particles (WIMPs). Event-by-event discrimination between
electron and nuclear recoils is achieved through simultaneous collection of charge
and phonon signals. The detectors are operated at cryogenic temperatures of 50 mK at
the Soudan Underground Laboratory. The latest results obtained by the CDMS-II
experiment are summarised, together with the constraints on light WIMPs from a
lowered 2 keV recoil energy threshold reanalysis of 8 germanium detectors. Future
plans to increase the sensitivity and total detector mass in view of the SuperCDMS
and GEODM experiments are also discussed.
