Technique for WIMP dark matter detection using pulse-shape discrimination in noble liquids

The performance of a dual-purpose liquid neon detector (CLEAN) for dark matter and low-energy solar neutrino interactions evaluated with Monte-Carlo simulations will be discussed. The projected sensitivity for CLEAN is less than 10$^{-46}$ cm$^2$ for the spin-independent WIMP-nucleon cross-section, and 1$\%$ uncertainty for the $pp$ solar neutrino flux measurement. The general technique of using scintillation pulse-shape discrimination in noble liquids will be discussed, and progress on a small-scale argon WIMP-dark matter experiment (DEAP) will be presented.
