Aiming to better understand the nature of the neutrino and the origins of matter in the universe
What is the nature of the neutrino? Why is it's mass finite, yet so tiny? Is it connected to the matter-antimatter asymmetry of the universe? In the quest to answer these and other questions, nEXO is the next generation experiment to search for neutrinoless double beta decay using liquid xenon target enriched with Xe-136. Proposed to be built at SNOLAB, Canada in one of the deepest underground labs in the world, nEXO is projected to have a half-life sensitivity of greater than 10^28 years. The collaboration itself consists of more than 180 physicists and engineers from 34 institutions around the world.

The nEXO time projection chamber (top left inset) allows measurement of energy and location of double beta decays.
Human silhouettes illustrate the scale of the nEXO detector, which will be built in a cavern two kilometers underground. The xenon, located in the center, is protected from radioactive background by a cylindrical copper vessel, a sphere of special fluid, and a water tank.
