The LEGEND experimental program searches for neutrinoless double beta decay in 76Ge-enriched high-purity germanium detectors operating in liquid argon. With a planned ultimate exposure of 1 tonne·yr and a target background index of 2E-4 cts/(keV·kg·yr) at Qββ = 2039 keV, LEGEND-200 is expected to reach a 3σ discovery sensitivity of 1E27 years half-life. The next generation experiment, LEGEND-1000, will operate 1000 kg of detectors and reach an expected discovery sensitivity of 1E28 years half-life, covering the inverted neutrino mass hierarchy. This talk will introduce LEGEND and discuss the production of two calibration isotopes that has been investigated at the Center for Experimental Nuclear Physics and Astrophysics at the University of Washington, an ARUNA institution.
