Dark Matter Search with Moderately Superheated Liquids
نویسندگان
چکیده
We suggest the use of moderately superheated liquids in the form of superheated droplet detectors for a new type of neutralino search experiment. The advantage of this method for Dark Matter detection is, that the detector material is cheap, readily available and that it is easily possible to fabricate a large mass detector. Moreover the detector can be made ”background blind”, i.e. exclusively sensitive to nuclear recoils. Proceedings of the 2 Workshop on The Dark Side of the Universe Rome, Italy, Nov.1995

Wimp Searches with Superheated Droplet Detectors: Status and Prospects
SIMPLE (Superheated Instrument for Massive ParticLE searches) employs superheated droplet detectors (SDDs) to search for Weakly Interacting Massive Particle (WIMP) dark matter. As a result of the intrinsic SDD insensitivity to minimum ionizing particles and high fluorine content of target liquids, competitive WIMP limits were already obtained at the early prototype stage. We comment here on the...
متن کاملA Superheated Droplet Detector for Dark Matter Search
We discuss the operation principle of a detector based on superheated droplets of Freon-12 and its feasibility for the search of weakly interacting cold dark matter particles. In particular we are interested in a neutralino search experiment in the mass range from 10 to 104 GeV/c2 and with a sensitivity of better than 10−2 events/kg/d. We show that our new proposed detector can be operated at a...

متن کاملFirst dark matter limits from a large-mass, low-background, superheated droplet detector.
We report on the fabrication aspects and calibration of the first large active mass ( approximately 15 g) modules of SIMPLE, a search for particle dark matter using superheated droplet detectors (SDDs). While still limited by the statistical uncertainty of the small data sample on hand, the first weeks of operation in the new underground laboratory of Rustrel-Pays d'Apt already provide a sensit...
متن کاملDARWIN: dark matter WIMP search with noble liquids
DARWIN (dark matter wimp search with noble liquids) is a design study for a nextgeneration, multi-ton dark matter detector in Europe. Liquid argon and/or liquid xenon are the target media for the direct detection of dark matter candidates in the form of weakly interacting massive particles (WIMPs). Light and charge signals created by particle interactions in the active detector volume are obser...
