The Cryogenic Dark Matter Search experiment (CDMS) : Status, future and recent detector development

Lundi 13 Décembre à 14h15

The Cryogenic Dark Matter Search experiment (CDMS) is seeking to detect WIMPs via their interactions in very low temperature germanium detectors. The main challenge of WIMPs direct detection consist of the low energy of interaction where most of the radioactive background is present. CDMS uses Ionization and athermal phonon measurement technique to discriminate WIMPs against the radioactive background. CDMS is currently the most sensitive experiment to WIMP nucleon interaction (For WIMP masses >70 GeV/C^2) worldwide. During this presentation I review the detection technique, current results and future plans of the CDMS experiment. In particular CDMS has recently developed new detector design (a.k.a the iZIP design) which will drastically improves its radioactive background rejection performance. I will describe the details of the CDMS new detector design and the results from the prototype characterization at the CDMS detector test facilities.
