Query: Large-Scale, Precision Xenon Doping of Liquid Argon   The detection of scintillation light from liquid argon is an experimental
technique key to a number of current and future nuclear/particle physics
experiments, such as neutrino physics, neutrinoless double beta decay and dark
matter searches. Although the idea of adding small quantities of xenon (doping)
to enhance the light yield has attracted considerable interest, this technique
has never been demonstrated at the necessary scale or precision. Here we report
on xenon doping in a 100 l cryogenic vessel. Xenon doping was performed in four
concentrations of 1.00$\pm$0.06 ppm, 2.0$\pm$0.1 ppm, 5.0$\pm$0.3 ppm, and
10.0$\pm$0.5 ppm. These measurements represent the most precise xenon doping
measurements as of publishing. We observed an increase in average light yield
by a factor of 1.92$\pm$0.12(syst)$\pm$0.02(stat) at a dopant concentration of
10 ppm.
