DEAP & CLEAN Detectors for Low-Energy particle Astrophysics

 The unique properties of scintillation light in liquid cryogen
 targets such as neon and argon provide an opportunity to realize
 conceptually simple, massive, and ultra-pure detectors of low-energy
 solar neutrinos and cosmological dark matter. I will discuss the status
 and scientific motivation in pursuit of WIMP dark matter and the 
 low-energy and dominant pp-solar neutrinos. Within this context, I will
 describe the program underway for the design and construction of two novel
 and complementary detectors dubbed DEAP (Dark matter Experiment with Argon
 and Pulse shape discrimination) and CLEAN (Cryogenic Low Energy Astrophysics
 with Neon).
