Description
Finding evidence of neutrinoless double beta decay would reveal the Majorana nature of the neutrino and give insight into the origins of the matter-antimatter asymmetry in the universe, the smallness of neutrino mass, and the symmetry structure of the Standard Model. The NEXT collaboration is developing a sequence of high pressure xenon gas time projection chambers with the aim of creating a ton-scale, very low background neutrinoless double beta decay search. NEXT-CRAB (Camera Readout And Barium tagging) demonstrates new designs that enable scaling NEXT beyond the ton scale and ultimately provide a background free signal, enabling measurements that probe the normal neutrino mass ordering. To do this we are employing several novel techniques, one of which is using direct VUV imaging of the electroluminescence with a TimePix3 camera and image intensifier. This poster will present the latest results of the first high resolution 3 dimensional tracks with an optical xenon gas time projection chamber where all the readout devices are outside the vessel. This technique improves radiopurity, reduces heat load, is easily scalable and opens the cathode plane for incorporation of barium tagging, a novel technique developed to distinguish each time the daughter nucleus of double beta decay is within the detector volume.
