Description
The LEGEND Experiment is designed to search for the neutrinoless double-beta decay of Ge-76, a lepton-number-violating process whose observation would establish the Majorana nature of neutrinos and provide clear evidence for physics beyond the Standard Model. Building off of the successes of the currently-running LEGEND-200 Experiment and the earlier generation experiments GERDA and the MAJORANA DEMONSTRATOR, the LEGEND-1000 Collaboration proposes to deploy one ton of detector material to reach unprecedented discovery sensitivity to half-lives beyond 10^(28) yr, fully probing the parameter space for mediation of this process by Majorana neutrinos with inverted-ordered masses. In this poster, we will provide an overview of the latest technical design for LEGEND-1000, highlight progress on construction activities already underway, and will discuss challenges related to reaching the sensitivity of the experiment.
