We propose the construction of a WIMP detector based on the technology of superheated freon-droplets dispersed in a polymerized gel. Tests with 3%-loading factory-made detectors spiked with ~(241)Am show that adequate sensitivity for ~(35)Cl and ~(19)F recoils can be achieved at energies as low as 4 iceV (in the case of ~(35)Cl) at 35°C. Efficiency and sensitivity curves are deduced for a wide variety of impinging particles from masses of 20 to 100 GeV/c~2. Piezo-clectric sensors oan detect droplet-tjubblo phase transition with 100% efficiency up to distances of 20 cm. A modular design of a large WIMP detector is proposed. With realistic contamination levels of detecting medium, a substantial gain in sensitivity can be envisaged over competing techniques, due to Hie total insensitivity of superheated liquids to low specific ionization radiations (α, β, and γ) and the availability of large volumes of inexpensive active components.
