From CDMS to SuperCDMS
نویسنده
چکیده
The Cryogenic Dark Matter Search (CDMS) and SuperCDMS experiments seek hypothetical weakly-interacting, massive particles (WIMPs) that could account for the majority of matter in the Universe, by means of cryogenic germanium detectors. We provide an update on the status of the SuperCDMS experiment, and discuss the joint CDMS-EDELWEISS analysis.

Recent results from the CDMS-II experiment
The Cryogenic Dark Matter Search experiment (CDMS) employs low-temperature Ge and Si detectors to detect WIMPs via their elastic scattering interaction with the target nuclei. The current analysis of 397.8 kg-days Ge exposure resulted in zero observed candidate events, setting an upper limit on the spin-independent WIMP-nucleon cross-section of 6.6× 10 cm (4.6× 10 cm, when previous CDMS Soudan ...
متن کاملPresent Status of the SuperCDMS program
The expected final reach of the Weakly Interacting Massive Particle (WIMP) search experiment CDMS-II by the end of 2007 is a WIMP-nucleon crosssection sensitivity of 2.1 × 10−44 cm2. To proceed further in our search, we have proposed the SuperCDMS Phase A project that would deploy 42 1-inch thick Ge detectors, at a site deeper than the location of CDMS II, and reach a desired sensitivity goal o...
متن کاملCharacterization of SuperCDMS 1-inch Ge Detectors
The newly commissioned SuperCDMS Soudan experiment aims to search for WIMP dark matter with a sensitivity to cross sections of 5 x lO^̂ ĉm^ and larger (90% CL upper limit). This goal is facilitated by a new set of germanium detectors, 2.5 times more massive than the ones used in the CDMS-II experiment, and with a different athermal phonon sensor layout that eliminates radial degeneracy in positi...
متن کاملThe SuperCDMS proposal for dark matter detection
Presently the CDMS-II collaboration’s Weakly Interacting Massive Particle (WIMP) search at the Soudan Underground Laboratory sets the most stringent exclusion limits of any WIMP cold dark matter direct-detection experiment. To extend our reach further, to WIMP-nucleon cross-sections in the range 10 46 10 44 cm, we propose SuperCDMS, which would take advantage of a very deep site. One promising ...

Background and objective : Clinical decision-making is an essential part of nursing practice, constantly used by nurses in order to take care of patients. While some studies have recognized that teaching the clinical decision- making skills has always accompanied problems, an important goal of baccalaureate nursing education is student nurses’ development of skilled clinical decision-making...
