【 摘 要 】

The SuperNEMO experiment will search for neutrinoless double β decay with a sensitivity two orders of magnitude greater than its predecessor NEMO-3, achieved through better energy resolution and unprecedented background levels. A Demonstrator module of the detector is currently under construction, due to begin data taking in 2015. A vital component of the detector is the tracker, a wire chamber made from 2,034 cells operating in Geiger mode. This is important for triggering, background discrimination, and measurement of the kinematic properties of the decay. The tracker production procedure and status is presented.
