Abstract

An ultimate liquid xenon dark matter experiment would be limited in its dark matter science reach by irreducible neutrino backgrounds. To achieve such sensitivity, other backgrounds that currently plague these detectors must be better mitigated, and extreme care must be taken in the design and construction phases. Historically, liquid xenon time projection chambers have scaled to larger target masses with great success. This paper gives an overview of challenges that need to be met for the next generation of detector to obtain a kilotonne$\times$year exposure. Such tasks include the procurement and purification of xenon, radiopure and reliable detector components, sensitive outer detector vetoes, powerful data handling and analyses, and an ability to operate stably for timescales of over a decade.
