Description
The NEXT collaboration is pursuing a phased program to search for neutrinoless double beta decay(0nubb) using high pressure xenon gas time projection chambers. Xenon gas detectors offer a key opportunity: the plausible implementation of single barium daughter ion tagging, an approach that may reduce radiogenic and cosmogenic backgrounds by orders of magnitude and unlock sensitivities that extend beyond the inverted neutrino mass ordering. In this poster I will present recent advances in the development of single ion barium tagging technology for high pressure xenon gas detectors based on single molecule fluorescence imaging (SMFI) using a novel high pressure gas microscope and custom-engineered organic fluorophores for dry functionality, single ion capture and imaging in a high-pressure xenon gas environments has been demonstrated. The high pressure, widefield, single ion imaging microscope is the first of its kind in the world and is a prototype sensor for integration into a future barium tagging high pressure xenon gas TPC experiment.
