### Description

The large difference between the time constants of the two scintillation pulse com- ponents of a noble liquid like liquid Argon or Neon provide a very reliable correlation between pulse shape and type of event. This pulse shape discrimination already pro- vides the power of rejecting a background $10^{8}-10^{9}$ times larger than the signal. A 400 kg LAr detector, MiniCLEAN, is currently under construction, and a 3.6 ton detector, DEAP-3600, under development. The pro jected sensitivities of these two Dark Matter detectors are illustrated. As the DEAP/CLEAN program is also for p-p solar neu- trino detection, the sensitivity to these neutrinos expected from future larger upgrades loaded with liquid Neon is also discussed.
