The NEXT Experiment

The Neutrino Experiment with a Xenon TPC~is an experiment designed to develop high pressure xenon gas time projection chambers to search for~neutrino less double beta decay of Xenon 136. The goal in creating these~TPCs is~to create both~a greater energy resolution and greater~discrimination of signal against the background noise. An optical~TPC is being developed where a~camera is~introduced~to capture images of the event. The images are stitched together to recreate an energy track, which in turn determines if a double beta decay occurred.~This presentation will cover the basic concepts observed in xenon time projection chambers with an emphasis on the optical time projection chamber.
