Contribution

It introduces a novel detector approach using superheated liquids for dark matter detection, emphasizing its cost-effectiveness and background discrimination capabilities.

Findings

Detector material is inexpensive and readily available.

Large-scale detector fabrication is feasible.

Detector is sensitive exclusively to nuclear recoils.

Abstract

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.
